Wireless Sensor Networks (WSNs) consist of large number of tiny sensor nodes, all of which have sensing capabilities. As sensor nodes are typically powered by nonrenewable batteries, energy efficiency is a critical factor in wireless sensor networks. Sensor nodes want to continue their lives with limited energy. Each of them using its own energy in minimum level and them aims to provide maximum efficiency to network. In this paper, the authors show that optimum packet length over data transmission at the data link layer. An example scenario is developed in OMNet simulation platform using IEEE standard 802.15.4. The optimal packet length is obtained in terms of energy efficiency.
