Traffic aware Multipath Communication for Time-Critical Applications in Underwater Acoustic Sensor Networks
Journal Title: International Journal of Management, IT and Engineering - Year 2012, Vol 2, Issue 7
Abstract
In this project, we propose an energy efficient and collision aware (EECA) node-disjoint multipath routing algorithm with multipath power-control transmission (MPT) scheme for Acoustic sensor networks. With the aid of node position information, the EECA algorithm attempts to find two collision-free routes using constrained and power adjusted flooding and then transmits the data with minimum power needed through power control component of the protocol. And also, we propose a new multipath power-control transmission (MPT) scheme, which can guarantee certain end-to-end packet error rate while achieving a good balance between the overall energy efficiency and the end-to-end packet delay. MPT smartly combines power control with multipath routing and packet combining at the destination. With carefully designed power-control strategies, MPT consumes much less energy than the conventional one-path transmission scheme without retransmission. Besides, since no hop-by-hop retransmission is allowed, MPT introduces much shorter delays than the traditional one-path scheme with retransmission. We conduct extensive simulations to evaluate the performance of MPT and EECA.
