Service availability ensures that a service with relevant information can be accessed properly by legitimate users in a timely manner,This paper aims to provide an overview of recent development of a security approach including the following three research issues;(1)risk analysis method providing wireless sensor network designers with a guideline to select a set of the security countermeasures that mitigates damages from possible availability attacks in the network,(2)management architecture for clustered sensor networks against distributed DoS attacks,and(3)secure middleware for group management based on the Jini service environment.For the first research issue.we suggest a method to estimate the damage caused by possible threat and the anticipated effectiveness of countermeasures. Regarding the second issue,we present a cooperative architecture of security management in order to protect access of legitimate users from distributed DoS attacks.Here,we consider high-level security mechanisms,including secure group management.In dealing with last research issue,a secure middleware has been developed and an experiment has been conducted to measure the reduced turn-around time compared with the standard Jini.

传感器网络中的目标跟踪需要较好地解决目标状态信息共享问题。针对DCTC、基于簇算法的不足,给出了基于连通支配集(CDS)构造汇聚树的方法。根据节点是否具备定位功能,目标状态信息在汇聚树内可以采用广播或单播的方式共享.由于汇聚树结构稳定,当目标切换覆盖区域时也能很好地实现连续跟踪.基于汇聚树的目标状态信息经逐级融合后到达基站,能极大地减少冗余报文传送,节省节点能量。
层次型路由协议对于传感器网络具有较好的适应性和节能性,针对现有路由协议在确定群首时忽略邻居节点的状态信息导致群内节点过早出现死亡的问题,提出了一种基于模拟退火微粒群选择群首的策略,有效避免了低能量和远距离的节点被选为群首的可能性。考虑Sink节点距离影响,提出了基于目标群首传输路径的路由协议,保证了群首间能量负载的均衡性。实验结果表明,模拟退火微粒群选择群首的策略有效延长了网络生存时间,基于目标群
