Ladder Routing: a Reactive Source Routing Protocol for Multi-Hop Data Transmission in Mobile Wireless Sensor Networks
Applications built upon mobile wireless sensor networks demand multi-hop data transmission between the sink node and any other far-away nodes. It's always not a good idea to broadcast the whole network for finding the best path to a specified far-away node because the broadcasting for route discovery consume too much amount of message exchanging between adjacent nodes in the network. In this paper, we propose a reactive source routing protocol, ladder routing, for finding the best path between the sink node and a specified node through a unicast kind of message exchanging. Ladder routing is implemented on each node in a parallel and distributed manner, which can help unicast route discovery message or data between the sink node and any other specified node along the best up-to-date path without introducing too much message consumption and time delay for route discovery and maintenance on demand.
