Most network applications such as pervasive computing, grid computing, P2P etc. can be viewed as multi-agent systems which are open, anonymous and dynamic in nature. Due to such nature multi-agent systems present potential threats in ensuring secured communication. One of the key feasible ways to minimize threats is to evaluate the trust and reputation of the interacting agents. Many trust models...
Optimization techniques for decreasing the time and chip area of adder circuits have been thoroughly studied for years mostly in binary logic system. In this paper, we provide the necessary equations required to design a full adder in quaternary logic system. We provide the design of a logarithmic stage parallel adder which can compute the carries within log2(n) time delay for n qudits. At last, we...

In this letter, we propose an incentivized relaying scheme for CDMA-based wireless mesh networks for broadband Internet access. This scheme is applied to entice the users, i.e., mesh clients, in range of the mesh infrastructure (mesh routers) to relay traffic to those clients that are in range with them, but are out of communication range of the mesh routers. To apply this mechanism, in-range clients...
A novel permanent magnet brushless DC motor drive using Z-source inverter is proposed and analyzed in this paper. This drive system provides advantages both for PMBDC motor and Z-source inverter and can be used in light electric vehicles and any other adjustable drive applications. The operation principle, system configuration and control method are presented. The mathematical model of the drive system...
