Throughput Analysis of Many to One Multihop Wireless Mesh Ad hoc Network

Mobile ad hoc networks are formed by co operative association of wireless nodes communicating with each other without the use of infrastructure. Every node acts as a router in the network and enables the communication between nodes that are separated over their radio range. Typically in ad hoc networks one or more nodes may act as gateway connecting to the external world. The node acting as the gateway becomes a sink and the throughput capacity of the network in such networks becomes crucial to maintain QOS. This paper investigates throughput of many to one scenarios in wireless mesh network using Ad hoc On Demand Vector (AODV) Routing Protocol. It is proposed to specifically investigate the throughput of one hop, two hop and three hops to the sink in the wireless mesh network. Investigations are also carried out to measure the throughput of the wireless mesh network when the route timeout variable in the AODV routing protocol is decreased.
