Abstract	:	In this thesis, I present the design and evaluation of new techniques for using directionalantennas to save energy and to bridge network partitions in a mobile ad hoc network. Thisthesis advocates close but simple collaboration between the routing layer and the MediumAccess Control (MAC) layer and shows through simulations, the effectiveness of this de-sign by modifying the Dynamic Source Routing (DSR) protocol, an on-demand ad hocnetwork routing protocol based on source routing. First, in order to save energy, RouteRequests and data packets are transmitted directionally. Extensive simulations show thatwithout affecting the behavior of the routing protocol noticeably, energy savings of up to75 is achieved. Second, in order to bridge network partitions, the routing protocol ismodified to use the ability of a directional antenna to transmit directionally over longerdistance as compared to an omnidirectional antenna, both antennas using the same power.Again, through simulations, the protocol is shown to be able to bridge network partitions.Also, when no partitions are present, the protocol is otherwise equivalent to the versionwithout the partition bridging modifications..........-....,....-...,..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..
