Collaborative Functioning for Underwater Acoustic Sensor Communication using AURP (AUV-Assisted Underwater Routing Protocol)

Abstract

Security has become one of the most essential requirements in any application domain of wireless sensor networks. It is highly required so that we can send data to an authenticated person on a secure channel ensuring all the aspects of security features like confidentiality, integrity, authentication, etc. are provided. But it is more essential in a domain like underwater acoustic sensor networks where the bandwidth is severely limited, the energy of sensors is limited and the propagation delay is very high and hence we have limited resources that must be utilized efficiently. In order to address these challenges, the proposed work focuses on a mobile agents based architecture consisting of secure co-operation of AURP (An AUV-aided underwater routing protocol) with the objective of providing maximum data delivery and minimum energy consumption. Further these mobile agents are encrypted and embedded in the AUV’s in their buffer for the data capturing process as these mobile agents can travel throughout the network via controlled AUV's. This work uniquely contributes a mobile agent based periodic approach for collecting data from various gateway nodes (cluster heads) of different clusters as specified in its itinerary using travelling sales person so that it covers all of them using an optimal amount of energy & processing them one by one and completing its itinerary and depositing the data to a sink and then repeating the same process again periodically when these AUV’s gets charged exploiting a solar energy. Each cluster has some members within one hop distance that have sensed some data which needs to be sent to a gateway node using encrypted mobile agents and only when some AUV's services are provided to that particular gateway node.
