To achieve efficient broadcasting with low interference and low energy consumption, each node optimizes its transmission power. In a tree-based topology, the message of node u can be overheard by nodes which are in the region of transmission radius of node u but not in a logical neighborhood of u. Therefore, some protocols have been proposed to reduce energy consumption by using overhearing. Since...
This paper presents a comparative analysis of different M-ary modulation schemes for wireless ad-hoc networks based on energy efficiency. It compares MPSK, MFSK, and MQAM on the basis of total energy consumption in the AWGN and non-frequency selective slow Rayleigh fading channel. Finally under detail mathematical calculations and simulation, we justify that the energy efficiency can be improved even...
