Distance-Energy Based Routing Algorithm with Priority Handling for UWSN
Chandra Prakash Gupta,
Underwater Sensor Networks (UWSNs) are being deployed for range of applications like collection of oceanic
data for research, underwater exploration, surveillance, disaster prevention etc. UWSNs are different from terrestrial
WSNs in terms of communication methods, network deployment and protocols used. In this paper, we present a localization
based routing algorithm with distance and energy consideration. In our scheme, sender node selects a forwarding
node on the basis of Routing Factor (Rf), a function of neighbor’s distance from destination node and its residual energy.
Energy is scaled within a range to take heterogeneity of node energies into account. Priority packets and routing tables are
also considered in our algorithm. Simulation results show improved performance of our routing algorithm in terms of
network lifetime and end to end delays.
Keywords: Acoustic signal, energy scale value, priority packets, routing, routing factor, routing tables, UWSN.
