Review on QoS aware improved AODV routing protocol in wireless mesh network

Abstract

Wireless Mesh Network (WMN) is emerging concept in wireless networks supporting broadband and high speed multimedia services, so network must guaranteed the Quality-of-Services (QoS). Wireless mesh network characterized by multihop wireless connectivity and frequently changing network topology therefore required efficient and optimal dynamic routing protocols with node authentication for preventing data form networking attacks. AODV is commonly used routing matrix for path discovery in Ad-hoc network. So that, implementing in wireless mesh network, AODV should improve for find optimal shortest path. In this paper, the QoS aware improved AODV routing protocol in wireless mesh network with the node authentication schemas has been discussed.

End to end delay distribution analysis and interference aware high throughput for Wireless Mesh Networks

“…The nodes processing the route discovery packets cache the path information, and the learned paths are used for packet routing. This approach reduces the overhead for long paths or large addresses such as IPv6 [2].…”

“…Mobile wireless networks can be classified into two types: infrastructure networks with fixed and wired gateways, and self-organized networks with no infrastructure, consisting of mobile radio nodes that don't require centralized system administration. The latter is well-suited for scenarios where immediate infrastructure is necessary [2].…”
