Large-scale hybrid networks that include wireless, wired, and satellite based communications are becoming common in both military and commercial situations. This paper describes a scalable simulation environment called GloMoSim (for Global Mobile Information System Simulator) that effectively utilizes parallel execution to reduce the simulation time of detailed high-fidelity models of large communication networks. The paper also presents a set of case studies that evaluate the performance of large wireless networks with thousands of nodes and compares the impact of different lower layer protocols on the performance of typical applications. 1. Introduction High-level design problems for the digital communication infrastructure in the military and commercial environment, are extremely challenging in a number of dimensions: the scale is large, network traffic is a mix of voice, data, and imagery; connectivity can change dynamically in unpredictable ways, and the quality of service requi...
