An Improved Service-Aware Multipath Algorithm for Wireless Multimedia Sensor Networks

摘要

Study the multipath transmission problems of the different services in Wireless Multimedia Sensor Networks (WMSN). To further effectively utilize networks resources, the multipath mechanism and service-aware is used to improve performance of OLSR(Optimized Link State Routing). A SM-OLSR(Service-aware Multipath OLSR) algorithm is proposed. An efficiency model is introduced, then multipath is built according to the routing ID and energy efficiency. Compared with other routing algorithms, simulation results show that the algorithm can provide service support for different data.
