Abstract	:	Ad hoc networking involves multihop, peer-to-peer communication between a groupof wireless mobile nodes in a network with a dynamically changing topology. Achievingenergy-efficient communication in such a network is more challenging than in cellular net-works due to the absence of a centralized access point that can administer power control.For example, the commonly used MAC protocol for ad hoc networks, the IEEE 802.1 1MAC protocol, uses a fixed power for all packet transmissions, for reasons of simplicityand to maintain the correct operation of its collision avoidance mechanism. In this thesis,I propose a distributed power-control based MAC protocol for ad hoc networks that usesvariable transmission power for the control (RTS, CTS) packets and the minimum requiredtransmission power for the DATA and ACK packets. The proposed solution, called PACA(Power-controlled Access with Collision Avoidance), improves both energy consumptionand throughput, by reducing the energy used for most packet transmissions and by al-lowing simultaneous transmissions by different........-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
