LORP : A Load-Balancing Based Optimal Routing Protocol for Sensor Networks With Bottlenecks

Free registration required

Executive Summary

The performance of Wireless Sensor Networks (WSNs) is tightly coupled with the geometric environment in which sensors are deployed. In a practical environment, bottleneck regions, for example bridges, may exist due to the existence of physical obstacles or energy depletion. In this paper, the authors propose a Load-balancing Based Optimal Routing Protocol (LORP). By finding the boundaries of holes in a sensor network with bottlenecks, LORP first identifies the bridges in the sensor field using their MACB algorithm. A centralized routing algorithm, "Balance-first" routing is then employed to prolong the lifetime of a WSN with bottlenecks. Theoretical analysis prove that LORP can improve the load distribution among different bridges, increase the lifetime of a WSN, and enhance the quality of network services.
