رویکرد توزیع کد ایمن و انتخابی برای شبکه های حسگر بی سیم چند جهشی

This paper proposes an efficient code distribution approach for multihop wireless sensor networks in heterogeneous environment. Reprogramming a sensor network necessitate to fulfil the changing application requirements, bug fix as it is impractical to reach the node once deployed. We are presenting an efficient code distribution scheme to update the running code in sensors over the air with secure authentication & completion verification. The experimental results shows how proposed approach sdeluge is efficient in terms of significant reduction in average completion & dissemination time, advertisement rate, average energy consumption consequently improvement in lifetime of the network.
