Abstract
Trust and energy consumption are challenging issues in WSNs. In earlier work, we proposed Trust-Based Cross-Layer Model (TCLM), which uses the direct and indirect observation of the nodes to compute the trust values and ACKs from data link layer and TCP layer are considered to update these values. In this paper, we introduce new scheme that consider the limited amount of energy for each sensor, and use multi levels for the remaining energy of the nodes and the degree of the priority which can be given to some of the packets. Also, we apply our proposed technique to TCLM to make it more efficient, called A Trust-Based Cross-Layer Energy-Aware Model. We present simulation results that demonstrate the effectiveness of the proposed scheme in both static WSNs. The new proposed model improves the performance of our earlier work by increasing the malicious detection ratio and decreasing the energy consumption. (C) 2015 The Authors. Published by Elsevier B.V.
