Mobile ad-hoc network (MANET) have emerged as a new systems and the most promising fields for research and development of wireless network. As the popularity of mobile device and wireless networks significantly increased over the past years, MANET has now become one of the most vibrant and active field of communication and networks. Due to severe challenges such as the open medium, unpredicted mobility of mobile nodes, distributed and cooperative communication and inherently constrained capabilities, which manifest exhaustible sources of power. Due to the increasing demand for high-speed data services, the limited and high cost of licensed, and the future MANETs are expected to be operating at frequencies greater than 2 GHz and most of the research work in the area has been done in the frequency range of 1-2 GHz.

In this thesis, a power conservation model is proposed. The proposed model is based on the conventional on-demand ad hoc routing protocols with the addition of a power model without incurring additional complexity on the existing MANET characteristics. The mobile nodes are able to computes their power their power status adaptively to decide if they are fit for packet forwarding and reception. The research illustrates the power conserving behaviour of the new technique using an analytical approach and also by computer simulations. The results have shown that power savings of more than 15% were achieved with not much delay in the network. The performance of the routing protocols in the presence of ambient noise in the network was analyzed as well as the sensitivity of MAANETs at a carrier frequencies above 2 GHz using the free space and two slope path loss model. Results show that at carrier frequency greater than 2 GHz the break point distance affects the throughput performance of the network, whilst at frequency less than 2 GHz, the throughput performance for the free space and two slope model was the same.
