The sensor network design approach normally considers the communication energy consumption for evaluating a communication protocol. This is true for the low power devices such as MICAz/MICA2 which do not consume a lot of energy for the data treatment. However, recently developed sensor devices for multimedia applications such as iMote2 do consume considerable amount of energy for data processing. In this article, we consider various scenarios for routing the data in wireless multimedia sensor networks by considering the local design parameters of devices such as PXA27x and beagleboard. The proposed routing solution considers node level optimizations such as data compression, dynamic voltage and frequency scaling (DVFS) for making a routing decision. The proposed approaches have been simulated to prove the effectiveness of the approach. |
