摘要：Directed diffusion protocol enables data-centric routing for smart home sensor network. However, traditional directed diffusion protocol makes all nodes participating in the routing process. This causes a lot of redundant data transmission which brings unnecessary energy consumption. In this paper, we proposed LDDP, a location-based directed diffusion routing protocol for smart home sensor network, which reduces the number of nodes involved in data forwarding by room-based partitioning algorithm. Simulation results show that LDDP has better scalability than traditional DDP. LDDP can save 76th percentile energy when the node number is 200 and the transmission times is 5000. When the network size is 250, LDDP can also brings 40kb/s network throughput gain than traditional DDP. © 2014 IEEE.
