The Unceasing Detection of Adjoining Nodes, Its Connectivity, Weakness Impact on Wireless Sensor Networks and Actor Networks

摘要

The continuous detection of sensor and actor nodes in wireless sensor actor networks (WSANs) is facing new challenges notably in coordination. In this paper, a survey has been made to categorize, and bring into perspective existing researches on continuous connectivity of sensor node and its impacts on coordination ranging from a node failure to disability of actor nodes to communicate with other actors permanently. Actor nodes with noticeable amount of high power can help weaker sensors in different scenarios such as data forwarding and routing and many sensors can help few actors in the regions that actors are sparsely deployed. Actor nodes can mobilise, carry and charge sensors during the detection of inter-actor network. From the knowledge acquired from the survey, we describe that actor node along with sensor nodes in a WSAN can cooperate to provide the continuous detection of sensor nodes when the network connectivity is affected by any of the sudden interferences.
