TL;DR: The basic building blocks of an ad hoc group communication scheme are focused on, which achieves multicasting optimal QoS efficiency OptiQ_Policy algorithm by tracking resource availability in a node's neighborhood based on resource reservations, which announces the required QoS before each session initiation.
Abstract: The major challenge faced by designers of ad hoc network is the deployment of end-to-end quality-of-service support mechanisms for streaming media services over an adhoc group network Group-oriented services over large ad-hoc networks has a big impact on the needs of streaming services communication in terms of mobility, quality of service (QoS) support and multicasting In Ad hoc networks, where such features are not embedded with its architecture, it is necessary to develop QoS multicasting strategies This paper focuses on the basic building blocks of an ad hoc group communication scheme, which achieves multicasting optimal QoS efficiency OptiQ_Policy algorithm by tracking resource availability in a node's neighborhood based on resource reservations, which announces the required QoS before each session initiation The primary quality of service (QoS) issues such as required bandwidth, message delay, traffic type and hop count per route improves the efficiency of streaming services over adhoc network Streaming services support voice, data and video traffic by assessing and adjusting for various levels of QoS The performance analysis is performed on functional prototype of QASAN ad hoc mobile wireless network with emphasis on service satisfaction for multiple group conference sessions The performance of QASAN network is well compared with QoS-aware versions of AODV [20] and TORA[17], well-known ad-hoc routing and limited QoS protocols Using the SPRUCE[23] bandwidth traffic gathering tool, with a set of C++ modules an extensive set of performance experiments were conducted for these protocols with QASAN on a wide variety of mobility patterns and reservation strategies

TL;DR: Context Aware Adaptive Fuzzy (COAAF) is a ‘context aware’ protocol, which is adaptive for variable services and network traffic intensity, and the behaviour of streaming services is found to be highly variable; hence, fuzzy approach is adopted.
Abstract: The need for an adaptive with support for context service aware Quality of Service routing scheme is always a major research challenge. The complexities of Mobile Ad hoc Networks are well surveyed, but traditional routing protocols do not focus on the context aware nature of services, which is highly required for dynamic change in service requirements. Context Aware Adaptive Fuzzy (COAAF) is a `context aware' protocol, which is adaptive for variable services and network traffic intensity. The behaviour of streaming services is found to be highly variable; hence, fuzzy approach is adopted. COAAF is simulated over NS-2 and its performance analyzed in comparison with AODV, DYMO and GPSR routing schemes.

TL;DR: This study has proposed to develop a Mobility and Bandwidth Aware QoS Routing Protocol for MANET, initially as a clustering process in CFSR, and contains a prehandshaking strategy to help each node be aware of activities of its neighborhood before the normal transmissions.
Abstract: Mobile Adhoc Networks (MANET) out of the many defies it is critical to guarantee quality-of-service, because of its complex distributed system. The problem of routing is based on a predefined set of customer preferences. In this study we have proposed to develop a Mobility and Bandwidth Aware QoS Routing Protocol for MANET. Initially as a clustering process in CFSR, the neighbour discovery procedure is used. It contains a prehandshaking strategy to help each node be aware of activities of its neighborhood before the normal transmissions. Next to this QoS routing is provided. Finally we are using bandwidth estimation technique in order to provide QoS support. The overall frame work reduces the collision with a minimized level of redundancy.

TL;DR: This chapter focuses on designing and developing QoS aware routing protocol for multi-hop VANET and SADVA, an adaptive fuzzy based QoS service oriented approach for VANet.
Abstract: An attempt in implementing on-demand, QoS supported Vehicular Ad hoc Network (VANET) routing algorithms has taken new dimensions. Delivering information in time to achieve reliability across vehicles (nodes) is still being a challenge among the VANET research groups. An effort to develop a QoS adaptive routing schemes using soft computing techniques is made in this research work. SADVA – An adaptive fuzzy based QoS service oriented approach for VANET is presented in this paper. The performance of SADVA is compared with AODV (Perkins, Royer, & Das, 2003), GV-GRID (Li, & Yu, 2007), DSR (Johnson, Maltz, & Hu, 2004), FSR (Gerla, 2002), DYMO (Chakeres, & Perkins, 2006), REDEM (Prabhakar, Sivanandham, & Arunkumar, 2011b), and QARS (Prabhakar et al, 2011a). SADVA employs fuzzy logic system to determine the vehicle’s speed over an effective time period for different types of service in use between multiple VANET nodes to engage or cooperate in communication. This chapter focuses on designing and developing QoS aware routing protocol for multi-hop VANET. Metrics such as number of packets received per second, percentage of packet loss and time for route establishment are used to analyse the network situation. Simulation test runs are carried out using Two Ray Ground propagation model where vehicular traffic is generated according to a Poisson process.

TL;DR: A logging instrument contains a pulsed neutron source and a pair of radiation detectors spaced along the length of the instrument to provide an indication of formation porosity which is substantially independent of the formation salinity.
Abstract: The Ad hoc On-Demand Distance Vector (AODV) routing protocol is intended for use by mobile nodes in an ad hoc network. It offers quick adaptation to dynamic link conditions, low processing and memory overhead, low network utilization, and determines unicast routes to destinations within the ad hoc network. It uses destination sequence numbers to ensure loop freedom at all times (even in the face of anomalous delivery of routing control messages), avoiding problems (such as "counting to infinity") associated with classical distance vector protocols.

TL;DR: An architecture for implementing scalable service differentiation in the Internet achieves scalability by aggregating traffic classification state which is conveyed by means of IP-layer packet marking using the DS field [DSFIELD].
Abstract: This document defines an architecture for implementing scalable service differentiation in the Internet. This architecture achieves scalability by aggregating traffic classification state which is conveyed by means of IP-layer packet marking using the DS field [DSFIELD]. Packets are classified and marked to receive a particular per-hop forwarding behavior on nodes along their path. Sophisticated classification, marking, policing, and shaping operations need only be implemented at network boundaries or hosts. Network resources are allocated to traffic streams by service provisioning policies which govern how traffic is marked and conditioned upon entry to a differentiated services-capable network, and how that traffic is forwarded within that network. A wide variety of services can be implemented on top of these building blocks.

TL;DR: The resource reservation protocol (RSVP) as discussed by the authors is a receiver-oriented simplex protocol that provides receiver-initiated reservations to accommodate heterogeneity among receivers as well as dynamic membership changes.
Abstract: A resource reservation protocol (RSVP), a flexible and scalable receiver-oriented simplex protocol, is described. RSVP provides receiver-initiated reservations to accommodate heterogeneity among receivers as well as dynamic membership changes; separates the filters from the reservation, thus allowing channel changing behavior; supports a dynamic and robust multipoint-to-multipoint communication model by taking a soft-state approach in maintaining resource reservations; and decouples the reservation and routing functions. A simple network configuration with five hosts connected by seven point-to-point links and three switches is presented to illustrate how RSVP works. Related work and unresolved issues are discussed. >
