A study on research issues and challenges in WSAN

Wireless Sensor and Actor Networks (WSANs) have greatly enhanced the existing Wireless Sensor Network (WSN) by its heterogeneous node structure. WSAN is a collection of static sensors and mobile actors. The actors are active elements with high processing, communication capabilities, and less constrained to energy resources than passive sensors. An actor performs actions in the event area based on the sensors information. The existing sensor network protocols may not perform well because of real time application of WSAN. However, these applications require energy and delay aware mechanisms to perform reliable actions in the event area. Unfortunately, these types of mechanisms in WSANs are still undeveloped. Hence, this paper analyzes the existing protocols, and challenges for WSAN.
