Description: This simulator simulates the radio transmission/propagation/reception, including collisions in ad-hoc radio networks, and the operation of the MAC-layer. Any application can be implemented on any number of motes. The radio definitions (propagation and MAC-layer) and the applications are plug-ins. For the time being three radio definition files are provided (radio_channel.m, radio_channel_sinr.m and radio_channel_Rayleigh_ND.m), with a set of applications (demo, flood1D, flood2D, collision_demo, spantree).

Description: 本文正是在研究WIMAX/802.16e协议和FMIPv6协议的基础之
上，提出了基于FMIPv6的WIMAX网络快速切换机制，该方案采用跨
层切换的思想，MAC层联合网络层同时进行切换，在链路尚未断开
之前即完成新转交地址(NCOA)获取等功能，从而加快了切换进程，
减小了切换时延和切换时的丢包率。在提出本切换机制的基础上，本
文在NSZ仿真平台上对所提出的切换方案做了系统性的性能仿真，通
过仿真结果验证了方案的可行性和优越性。

introduction for the basic knowledge and research in MIPv6 and FMIPv6
protocol is given. A fast handover scheme of WiMAX network which
based on FMIPv6 protocol is suggested, which implements the fast
handover at IP layer associating with MAC layer at the same time.
scheme minimizes handover latency by predicting and preparing

the
impending handover in advance. Finally, simulation are carried out to
evaluate the performance of this fast handover scheme. The result of the
simulation shows that the fast handover scheme has good performance.
