....library. To decode this pointer to its original type, the C operator dynamic cast is used. Decoding the pointer to any other type will result in a null pointer, which can be detected by the component at runtime. 59 4. 5 PCS Simulation Using CORSA A PCS (Personal Communication Service) network [14, 11] is composed of a number of geographically distributed radio base stations. The PCS network simu lation involves two object types: cell and portable. The portables, carried by users in the coverage area (or cell) of a base station can use the channels assigned to that station. The number of ....
....is said to occur. In this case the portable releases the occupied channel to the old cell and then attempts to get a channel from the new cell. 4.5. 1 Two Reusable Components In this PCS simulation experiment, we adopt a partition scheme different from those normally used for parallel simulation [14, 11]. A cell component simulates all the cells, that is, it processes all the requests of channel allocation and releases. A portable component simulates all the portables. This partition scheme is difficult to be parallelized, but is well suited for the purpose of demonstrating the advantages of the ....

.... Mellow University has created a set of wireless and mobile extensions to NS that provide a more detailed model of the physical and link layer behavior of a wireless network and allow arbitrary movement of nodes within the network [7] Other network simulation tools include MobSim [27] SWimNet [5] and GloMoSim [33] A parallel environment for the simulation of mobile wireless network systems, based on the parallel simulation language Maisie [3] has been presented in [26] Discrete event simulators are great tools for overall network performance simulations and other more theoretical ....

....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 ....

....18, 19, 20] the e ect of di erent call models and portable movement patterns are studied. The models are implemented using distributed optimistic Time Warp simulation mechanism. There are similar studies that make use of either optimistic approach [116] or conservative synchronization approach [74, 11, 12, 13]. Albeit important in studies of general network performance and capacity, the above teletrac models assumes a great simpli cation of the real systems in which radio channel models that include signal propagation and interference e ects are not studied in detail. Modeling increasing level of ....

....Internet protocols. The scalability of the simulator to very large networks will be achieved primarily by exploiting parallelism on state of the art parallel computers. Parallel simulation of wireless networks has previously been studied primarily in the field of personal communication networks [4][6] 8] 10] In this paper, we develop detailed models of the protocol stack that is necessary to support multihop wireless communication in a mobile network. In particular, we develop high fidelity models of the various protocols used at the transport, routing, and MAC layers. We investigate the ....
