Intelligent Actor Mobility with Event Tracking in Wireless Sensor and Actor Networks

Abstract

A wireless sensor and actor network (WSAN) refers to a heterogeneous network primarily composed of sensor and actor nodes. A sensor is the part of the wireless network to sense the event to be occurred in the network. While actor is the entity that performs the networking related functionalities like receiving, transmitting and processing the data. The idea of mobile actor is the new concept in the WSANs research, which helps to take the most efficient action and provides energy and time efficient data collection. Two intelligent models were introduced previously, the static mobility model which uses the cluster information of a sparsely connected networks and another is dynamic mobility model designed on the basis of statistical model for the fixed duration events. Therefore, transmission of event detection information to the actors is one of the major concerns of WSANs. So, the Coordination and Communication between the actors must be managed properly. This paper addresses the actor-actor coordination for the timely responses to the events reported by the sensors in sparsely connected network of WSAN. Furthermore, this paper provides an event tracking algorithm to target the maximum tracked events.
