To save network node energy consumption and reduce data transmission delay in streetlight monitoring system
a chain routing algorithm for wireless sensor network(CRASMS)was proposed. The algorithm divided the monitoring region into several clustering regions according the information of nodes and monitoring region
successively and circularly selected a node to the cluster head node in each clustering region
established the star network in each cluster by the communication of cluster head node and sensor node. Finally
cluster head node received the data of sensor nodes
used the data fusion algorithm to reduce data redundancy
transmitted the fused data to sink node with multi-hop routing among cluster head nodes and transmitted the client's commands to the controlled nodes. The simulation results show that CRASMS algorithm keeps the advantage of PEGASIS algorithm in terms of energy consumption and the advantage of LEACH algorithm in terms of data transmission delay
overcomes the lack of PEGASIS algorithm in terms of data transmission delay and the lack of LEACH algorithm in terms of node energy consumption. It keeps the average node energy consumption and the average data transmission delay at a low level. Under certain conditions
CRASMS algorithm outperforms LEACH and PEGASIS algorithms.
