摘要：this paper is based on the performance in duality of network capacity and network lifetime in wireless sensor networks. The paper works on SLPPA approach. Where, each node to be utilized in an efficient manner to forward the packets among the nodes to the basestation such that the total throughput (capacity) can achieve an optimal point subject to common lifetime requirement on all nodes without requiring any energy reservation during each iteration. It solves both flow routing and rate allocation problems. But, the fairness issue in information collection and identity to the nodes are not considered. So, this paper is an extension of the referred paper for providing authentication and confidentiality among nodes to prevent from malicious nodes along with the duality performance metrics. A onetime dynamic key is employed for one packet to verify the authentication and different keys are used for the successive packets of the stream to provide confidentiality. The sensed data is encoded using a scheme, based on a permutation code generated by the RC4 encryption mechanism.
