Energy, Traffic Load, and Link Quality Aware Ad Hoc Routing Protocol for Wireless Sensor Network Based Smart Metering Infrastructure:

Abstract: Electricity industry is in the midst of revolutionary transition from outdated ageing power infrastructure to an intelligent sophisticated smart grid network utilizing modern communication technologies to enhance power generation, transmission, distribution, and consumption. Smart metering infrastructure is an integral part of the smart power grid revolution. Smart meters, in addition to their primary billing functions, serve as distributed Wireless Sensor Network (WSN) nodes for enhancing grid reliability. Existing ad hoc routing protocols are based on single routing criterion such as hop count. This single routing metric approach can overload and deplete resource constrained smart meters along preferred paths. A protocol is needed which is aware of energy level and traffic congestion of smart metering nodes. In addition, protocol should select route based on link quality for optimal routing. In this paper, a novel WSN ad hoc routing protocol ETL-AODV is proposed for reliable and energy efficient communication of smart metering nodes. Three simulation based case studies are conducted to analyze the performance of the proposed protocol, and relative comparison is provided based on four metrics: (i) packet delivery ratio (PDR), (ii) normalized routing load (NRL) (iii) average energy consumption and (iv) average end-to-end delay.

Multipath Power Sensitive Routing Protocol for Mobile Ad Hoc Networks

Abstract: Mobile Ad hoc Networks are characterized by multi-hop wireless links, without any infrastructure, and frequent host mobility A plethora of routing protocols has been proposed A class of routing protocols called on-demand protocols has recently gained attention because of their efficiency and low routing overhead As the mobile nodes in the network work on low power batteries, the need to take into account their power consumption arises This paper focuses on a particular on-demand routing protocol, called Dynamic Source Routing, and shows how an efficient heuristic based Multipath technique can improve the mean time to node failure and maintain the variance in the power of all the nodes as low as possible In the Multipath Power Sensitive Routing Protocol (MPSR) every node in the network is treated equally and the overall network is stable for a long time An interesting feature of using this protocol is that the end-to-end packet delay does not increase significantly The results of extensive simulation show that the performance of MPSR protocol is on an increasing trend as mobility increases when compared to the Dynamic Source Routing

A hierarchical routing protocol based on AFSO algorithm for WSN

Abstract: Wireless sensor networks (WSN) will enable the reliable monitoring of a variety environment for both civil and military applications. These networks require robust wireless communication protocols for the purpose of balancing the load and prolonging the network lifetime. In this paper, we propose a novel hierarchical routing protocol based on artificial fish swarm optimization (AFSO). Utilizes AFSO algorithm in cluster formation phase, its main object is to solve the NP-hard problem of finding k optimal clusters according to the given rules. The performance of the novel protocol is compared with the well known cluster-based protocol LEACH and LEACH-C. As the experiment results shown, the protocol can not only improve system lifetime but also prevent the networks form seriously energy consumption.

Alternate path routing in mobile ad hoc networks

Abstract: This research used a custom event-driven network simulator to evaluate alternate path routing's (APR's) behavior in mobile ad hoc networks (MANETs) In particular, it investigated how much route-diversity is inherent in typical ad-hoc networks, and the ability of a globally reactive routing-protocol (such as the zone routing protocol) to capture and utilize that route diversity It then explored the end-to-end capacity improvements provided by APR Results indicate that APR's benefit is highly dependent on both the network topology and the channel access methods
