Permanent Relocation and Self-Route Recovery in Wireless Sensor and Actor Networks

Khalid Mahmood, Muhammad Amir Khan, Mahmood ul Hassan, Munir Shah, Muhammad Kashif Saeed

چکیده

Wireless sensor and actor network’s connectivity and coverage plays a significant role in mission-critical applications, whereas sensors and actors respond immediately to the detected events in an organized and coordinated way for an optimum restoration. When one or multiple actors fail, the network becomes disjoint by losing connectivity and coverage; therefore, self-healing algorithm is required to sustain the connectivity and coverage. In this paper two algorithms; Permanent Relocation Algorithm for Centralized Actor Recovery (PRACAR) and Self-Route Recovery Algorithm (SRRA) for sensors have been proposed for connectivity and coverage. The effectiveness of proposed technique has been proved by realistic simulation results which ensure that our proposed technique better handles the connectivity and coverage. Keywords—Wireless sensor and actor networks; connectivity restoration; node mobility; route recovery node relocation
