Poster: Contention-based distance-vector routing for mobile ad-hoc networks

2004
Conference Papers

Abstract

Position-based routing protocols forward packets in a greedy manner from source to destination without having to maintain routes through the network. Contention-based routing strategies improve upon position-based routing in that they do not even require to maintain neighbor tables at the nodes. This makes them very robust in highly mobile networks. However, neighbor tables are essential in the recovery mechanisms that are used when greedy routing fails. In this poster proposal we outline Contention-Based Distance-Vector Routing (CBDV), a recovery strategy for contention-based routing protocols that works when no neighbor tables are present. We describe the basic idea and give a simulative analysis of its performance.

Wireless ad hoc network

A wireless ad hoc network (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes. The determination of which nodes forward data is made dynamically on the basis of network connectivity and the routing algorithm in use.

Network congestion

Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of congestion is that an incremental increase in offered load leads either only to a small increase or even a decrease in network throughput.

Communication protocol

A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics, and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages.
