ALBAR-H: Load Balancing Around Holes in Wireless Sensor Networks

In wireless sensor networks the formation of hole is inevitable because of the structure of the sensor networks. When a hole is formed reliability is decreased. With the formation of holes in sensor networks quality of service decreases eventually. Network coverage is an important factor to detect a specified area. In order to maintain the coverage quality of the sensor networks, the authors propose a light weight protocol, ALBAR-H which is a variant of ALBA-R mechanism to detect localization errors in the sensor networks.
