code.rar - Wireless Sensor Networks (WSNs) are comprised of thousands of sensor nodes, with restricted energy, that cooperate
to accomplish a sensing task. Various routing Protocols are designed for transmission in WSNs. In this
paper, we proposed a hybrid routing protocol: Zonal-Stable Election Protocol (Z-SEP) for heterogeneous WSNs.
In this protocol, some nodes transmit data directly to base station while some use clustering technique to send
data to base station as in SEP. We implemented Z-SEP and compared it with traditional Low Energy adaptive
clustering hierarchy (LEACH) and SEP. Simulation results showed that Z-SEP enhanced the stability period
and throughput than existing protocols like LEACH and SEP.,2013-12-21 12:15:13,下载43次
