Wireless Sensor Network Routing Algorithm Design And Application Research

In recent years, Wireless Sensor Network (WSN) has emerged as a promising field of research, leading to a great application potential. But all of these applications have to rely on reliable data transmission, so the routing protocol for WSN based on specific applications has been a hot research field. In this thesis, an overview of the routing algorithm for static sensor networks, mobile sensor networks, and vehicular mobile sensor network is given first, and the author proposes a packet-delivery condition aware routing (PCAR) algorithm for vehicular mobile sensor network with the purpose to use direct metrics to build a high quality route. It uses packet delivery ratio and average packet delay time as the metrics for calculating optimal route. Simulations based on NS2 platform are also conducted, and the results demonstrate that PCAR scheme outperforms GPSR and GPSR-L, in terms of average packet delay time, packet loss ratio, and packet delivery ratio. Finally, based on the previous theoretical research, the author analyzes and modifies the routing protocol in ZigBee protocol stack, and then presents an intelligent indoor light control system based on ZigBee sensor network, the experiment shows that the system can work automatically, adjusting lighting mode according to indoor scene changes.
