Timeout-based Information Forwarding Protocol for Wireless Sensor Networks

초록

Recent wireless microsensor network protocols provide more flexible leverage to the applications with dynamically changing topology, but they should be designed to overcome energy constraints, bandwidth limit, and system latency. Thus, microsensor network protocols should be effective both in energy and latency. In addition, they should be evaluated through designated tools at each level of networking characteristics. This paper proposes a new Timeout-based Information Forwarding (TIF) protocol for wireless sensor networks. It uses a relatively simple logic to forward data packet with multi-hop fashion to reduce overall network energy consumption. The TIF protocol has been implemented into network evaluation tool, called TIE/MEMS, and provide design strategy for distributed wireless sensor network systems needed for various emerging applications. Simulated results show that TIF protocol has low energy consumption and provides design guideline between energy consumption and latency according to number of hops by adjusting weight values in the timeout function.
