....stations within hearing range. Issues of power consumption and access control loom large in these designs, and routing strategies have an especially important in uence on the system s performance, and ultimate lifetime. Borrowing design elements from other network simulators, such as WiPPET [19], GloMoSim [7] SSFNet [13] and x Kernel [26] SWAN uses the ISO OSI stack model and provides a standard abstraction for building, at each sensor station, a protocol graph, which consists of a stack of protocol sessions each modeled as a stand alone protocol module. The design has its advantage ....
....and so the small lookahead which is adequate for GloMoSim s detailed radio simulations is inadequate for us. GloMoSim and SWAN are among the most current re ections of work on parallelized wireless simulation. Interest in the area has been active in recent years, examples of relevant work are [8, 9, 10, 12, 20, 22, 15, 19]. Emphasis and problems considered vary from project to project. A common theme in the list just cited is an interest in simulation of cellular communications. This problem has di erent radio characteristics than does ad hoc sensor networks, principally because sensor networks use very low power ....

....of two major kinds of interacting submodels: Node Model and Environment Model. 49 An instance of Node Model represents a mobile station. There can be as many instances as the number of mobile stations in the wireless network. Borrowing the design from other network simulators, such as WiPPET [53], GloMoSim [7] SSFNet [29] and x Kernel [94] the Node Model provides a standard abstraction for building protocol graph, which consists of a stack of protocol sessions each modeled as a stand alone protocol module. The design has its advantage in that these modules are insulated from ....
