Abstract:
Tiny sensor nodes that can sense their vicinity and communicate among themselves constitute the wireless sensor networks. These sensor nodes run on battery and are usually deployed in harsh environments. So energy efficiency is always a design issue for wireless sensor networks. Recently many energy efficient techniques were developed for routing. These techniques increased the network lifetime but compromised the delay metric. In some applications of wireless sensor networks like environment monitoring, intrusion detection etc delay is not tolerable at all. In this paper, self knowledge technique is implemented along with SCHP(sub cluster head protocol) to reduce the delay incurred due to link stability problem in SCHP. With self knowledge each node has information about its neighbors. The sender sends data according to the receiving capacity of the receiver which gives better link stability. Simulation results show that SCHP with self knowledge has lower delay and energy spent than SCHP and other network structure algorithms like top-down approach and bottom up approach.
