A novel routing technology based on circle and wedge for wireless sensor network

In this paper, a novel routing technology based on circle and wedge trained for wireless sensor networks is proposed to extend network lifetime and to reduce transmission delay. The routing protocol based on hierarchical architecture called CWR protocol need not the routing table, which saves lots of energy and cache of the sensor, also reduces the delay of looking for routing information. To solve the local routing for the same sector district, we present the new energy-efficient access point (AP) election algorithm, local position resolution protocol (LPRP) and the network position translation(NPT), which is cooperated with to support CWR protocol in the AP. An important by-product of the routing protocol is that we propose a new method to balance energy consumption and to keep approximate network wide energy equivalence by replacing AP with Backup AP when the AP is exhausted. We continue to describe each routing pathpsilas energy consumption in a wedge, and the whole sensor network deployment of energy is to be understood and improved accordingly. The simulation results show at last that the performance of our CWR protocol is better than the otherspsila under the condition of the system architecture for WSN trained (AWT).
