Abstract

In our earlier work, Network-Centric Optimal Hybrid Mobility for IPv6 wireless sensor networks, in which the work sought to control mobility of sensor nodes from an external network was proposed. It was a major improvement on earlier works such as Cluster Sensor Proxy Mobile IPv6 (CSPMIPv6) and Network of Proxies (NoP). In this work, the Network-Centric optimal hybrid mobility scenario was used to detect and fill sensing holes occurring as a result damaged or energy depleted sensing nodes. Various sensor networks self-healing and recovery, and deployment algorithms such as Enhanced Virtual Forces Algorithm with Boundary Forces (EVFA-B); Coverage - Aware Sensor Automation protocol (CASA); Sensor Self-Organizing Algorithm (SSOA); VorLag and the use of the use of anchor and relay nodes were reviewed. With node density thresholds set for various scenarios, the recovery efficiency using various parameters were measured. Comparably, our method provides the most efficient node relocation and self-healing mechanism for sensor networks. Compared to Sensor Self-Organizing Algorithm (SSOA), Hybrid Mobile IP showed superiority in coverage, shorter period of recovery, less computational cost and lower energy depletion. With processing and mobility costs shifted to the external network, Hybrid Mobile IP extends the life span of the network.
