Abstract
Wireless Sensor and actor networks (WSANs) are the most promising research area in the field of wireless communication. It consists of large number of small independent sensor and powerful actor nodes equipped with communication and computation capabilities. Actors gather sensor’s data and react collaboratively to attain application particular assignments. A powerful connected inter-actor network is required to coordinate its operations. Actor node may fail due to the battery depletion or any hardware failure and this failure may divide the network into disjoint segments. This problem can degrade the network performance but also reduce the efficiency and effectiveness of the network. To restore the network into its original state, the researchers have proposed many connectivity restoration techniques during last few years. This paper provides a brief review of the existing connectivity restoration techniques for WSANs with their advantages and limitations.

Summary
Wireless Sensor networks (WSNs) have gained a substantial attention in recent years. The wide spectrum of WSNs applications has open many research areas and it is being considered the most substantial modern technologies of recent times. Node’s mobility can improve the overall performance of the network like connectivity, coverage and network lifetime [2]. These recovery processes cause messaging overhead as well. These algorithms deal with single actor node failure, and do not consider the efficiency of the resources and lack of emphasis on recovery time. The main objective of the review paper is to provide a brief review of the connectivity restoration techniques for wireless sensor and actor network. This review paper provides a comparison of different connectivity restoration techniques for WSAN with their objectives, advantages and limitations.
