Active High Dynamic Sensor Routing Protocol Using Time Division Multiple Access

Concerning the poor reliability of most existing routing protocols used in mobile wireless sensor networks(MWSN), active high dynamic sensor routing(AHDSR)based on MWSN is proposed. The proposed protocol is based on a simple hop metric, which enable the data to remain dynamic and robust when routing the sink node in the mobile environment. AHDSR maintains a gradient metric in mobile environments by using a global time division multiple access(TDMA)MAC layer. It also uses the technique of blind forwarding to pass messages through the network in a multipath manner. The effectiveness of the proposed protocol is verified by the simulation results. Compared with other similar methods, data packet delivery ratio, average packet delay throughput and overhead of the proposed protocol are more suitable for a variety of mobile network scenarios.
