TL;DR: The HOLSR mechanism is derived from the O LSR protocol; however, unlike OLSR, the HOLSR protocol takes advantage of different mobile node capabilities to reduce the routing control overhead in large heterogeneous ad hoc networks, thus improving the performance of the routing mechanism.
Abstract: This article reviews the hierarchical optimized link state routing (HOLSR) mechanism for heterogeneous mobile ad hoc networks. In this work a heterogeneous mobile ad hoc network is defined as a network of mobile nodes that are characterized by different communications capabilities, such as multiple radio interfaces. The article focuses on proposing the HOLSR protocol. The HOLSR mechanism is derived from the OLSR protocol; however, unlike OLSR, the HOLSR protocol takes advantage of different mobile node capabilities to reduce the routing control overhead in large heterogeneous ad hoc networks, thus improving the performance of the routing mechanism.

TL;DR: The challenges of realizing video streaming over MANETs are identified, and the proposed techniques are analyzed and classify, indicating that the research domain suffers from a problem of comparability.
Abstract: Developments in mobile devices and wireless networking provide the technical platform for video streaming over mobile ad hoc networks (MANETs) However, efforts to realize video streaming over MANETs have met many challenges, which are addressed by several different techniques Examples include cross-layer optimization, caching and replication, and packet prioritization Cross-layer optimization typically leverages multiple description video coding and multipath routing to provide the receiver(s) sufficient video quality Caching and replication add tolerance to disruptions and partitioning In this paper, we identify the challenges of realizing video streaming over MANETs, and analyze and classify the proposed techniques Since 65 % of the identified involve cross-layering design, we study the distribution of joint optimization and parameter exchanges Due to the importance and complexity of evaluating the techniques, we analyze the common methods, indicating that the research domain suffers from a problem of comparability

TL;DR: In this article, a contention-based media access mechanism and self-allocating bandwidth within a wireless mesh network by dynamically modifying one or more contentionbased transmission control parameters is presented. But the routing nodes determine a hop count and adjust one ormore contention parameters based at least in part, on the hop count.
Abstract: Methods, apparatuses and systems directed to facilitating load balancing and bandwidth a) location in wireless mesh networks. Generally, according to one implementation of the present invention., routing nodes implement a contention-based media access mechanism and self-allocate bandwidth within a wireless mesh network by dynamically modifying one or more contention-based transmission control parameters. The routing nodes determine a hop count and adjust one or more contention parameters based at least in part, on the hop count.

TL;DR: Extensive studies simulations for DSR, AODV, LAR1, FSR and WRP in homogenous and heterogeneous networks that consist of different nodes with different resources showed that while all protocols perform reasonably well in homogeneous networking conditions, their performance suffer significantly over heterogonous networks.

TL;DR: In this article, a routing node computes a routing metric, which is based on the computed route cost and hop count, and selects a preferred neighbor as the parent routing node based on a best routing metric.
Abstract: Methods, apparatuses and systems directed to facilitating increased throughput in wireless mesh networks. Generally, according to one implementation of the present invention, routing nodes in a wireless mesh network combine metrics corresponding to the link and network layers to select a route to a root node in the wireless mesh network. In one implementation, for each neighbor, a given routing node computes a routing metric, which is based on the computed route cost and hop count, and selects a preferred neighbor as the parent routing node based on the best routing metric.
