INTEGRATING ROUTE OPTIMIZATION INTO DATA TRANSMISSION FOR RELIABLE ROUTING IN WIRELESS SENSOR NETWORK

Abstract

In this report, Aiming at reliable data delivery in wireless sensor network a novel routing protocol. This protocol differs from the traditional protocol as it integrates path quality information collection into the data transmission and achieves route optimization dynamically and adaptively. Integrating route optimization works in a “monitor and adjust” way means every route is selected for every data packet independently according to the route selection probability vector (RSPV). Real time quality information is gathered in the course of packets transmission and fed back by the sink periodically. Using the interval estimation, Source node identifies and filters out the paths of low quality and adjusts the route selection probability vector according to that. A simulation result in semi-static and dynamic environment show integrated route optimization is competent to deal with the adverse, dynamic, bandwidth constrained wireless sensor network and outperform typical reliable routing protocol in both energy efficiency and reliability.
