摘要：This paper presents a an environment monitoring systems (EMS) architecture based on sensor networks, which includes a new adaptive clustering scheme and a multi-hop routing algorithm, called sensors-enabled event routing architecture (SEERA). By monitoring the received signal power from other nodes, each node estimates the number of active nodes in realtime and computes its optimal probability of becoming a cluster head (CH) in order to minimize the amount of energy consumed in both intra- and inter-cluster communications. In order to prolong the network lifetime, the multi-hop routing algorithm is designed to be both energy-efficient and power-aware, based on the clustering architecture. The new clustering and routing algorithms scale well and converge fast for large-scale dynamic sensor networks, as shown by the simulation results.
