At the present time, wireless sensor networks are becoming more and more common and energy consumption is a key factor in the deployment and maintenance of these networks. This thesis compares non-SFN multi-hop and a single frequency network (SFN) or cooperative diversity algorithms with respect to the energy consumed by the nodes. Since the nodes have limited power capacity it is extremely important to have an efficient algorithm. In addition, the behaviour of the network when SFN is employed must be studied and advice offered with regards to improvements in order to achieve preferential results. The effect on the network regarding macro diversity is positive but, the battery energy consumption is still higher and has a drainage effect on the network for simple multi-hop. The report will include background information regarding mobile ad-hoc networks and the relationship with cooperative diversity. It will also deal with how different algorithms affect the energy consumption in multi-hop networks. Simulations will also be presented in Matlab plots for two single frequency network scenarios against a simple multi-hop regarding node energy during the network discovery and decline. Results will include comparative figures which are followed by a discussion concerning the simulation results and its effects. The applications for wireless sensor networks include area monitoring, environmental monitoring, data logging, industrial monitoring, agriculture and the idea can additionally be used for wireless radio and TV distribution. The simulations have been conducted for cooperative diversity algorithms (SFN-A and SFN-D) against an algorithm which does not use cooperative diversity in Matlab. The node energy consumption is compared for both scenarios with regards to both network reachability and decline. The node power is analysed during the reachability of the network from the start to attaining 100% of the discovered network. During network decline, the behaviour of the node energy is studied for algorithms with SFN-A, SFN-D and non SFN. Also, the number of times node transmission occurs with regards to node discovery is also analysed.
