A Simulation Environment for Ad Hoc Networks Using Sector Subdivision

In this paper a new model for communication in MANETs will be presented: Instead of omnidirectional transmissions, as assumed in most papers and all existing systems, the members are allowed to submit data in a fixed number of different directions (sector subdivision) and to adjust the transmission power in each sector separately. A simulation environment (Simulation Environment for Ad Hoc Networks, SAHNE) will be presented that allows simulation of communication strategies in MANETs that use sector subdivision, and simulation results will be shown where communication paths are selected via hop-minimization or geometric spanner properties. SAHNE is based on C++ and common libraries, which ensures that it can be used on many different platforms. The experiments show the influence of different parameters in realistic szenarios, and using geometric routing seemed to be better than using hopminimization.
