Transmission Policy for Wireless Sensor Networks |
|
|
Transmission policy guides sensor nodes in selecting communication range(s) and respective duty cycle(s) to send data traffic towards the sink. To prolong the overall lifetime, recent studies show that transmission policy plays a vital role in addition to energy efficient topology control, routing and MAC protocols. Existing transmission policies, however, cause an extremely unbalanced energy usage among sensors due to non-uniform concentration of data traffic and their varying distances from the sink. We propose a transmission policy and determine the optimal transmission ranges and their duty cycles by formulating network lifetime as an optimization problem. Our proposed policy performs substantially better in terms of network lifetime and energy distribution than the existing transmission policies irrespective of network parameters. |

I am currently doing my PhD degree under the supervision of Dr. Joarder Kamruzzaman at Gippsland School of Information Technology, Monash University, Australia. I obtained my B.Sc. and M.Sc. in Computer Science and Engineering degrees from the Dept. of Computer Science and Engineering (CSE) of Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh. Before coming to GSIT, I was working as an Assistant Professor at the dept. of CSE, BUET and currently I am on study leave. My research interests include Algorithms, Graph Theory, Wireless sensor networks and ad hoc networks. |
