Kernel Weighted Scheme for Improving Mobile Sensor-Node Connectivity

In the past decade, interest in fixed wireless sensor networks shifted to reflect current developments in mobile sensor networks with prominent mobility. However, due to the issues caused by joining or leaving the sensor network, a mobile sensor node is vulnerable to lose its connectivity. To regain its connectivity, a mobile sensor node must spend more time and energy to perform the reassociation procedure, resulting in an efficiency decay of the sensor network. To overcome this problem, we design a kernel moving average scheme based on the quality indicator prediction in the media access layer. The proposed scheme can reduce the nonconnectivity time of mobile sensor node through early performance of the reassociation procedure.
