说明：  Matlab中对建立好的网络进行节点/连边随机、蓄意攻击，用最大连通子图、网络效率来衡量网络的抗毁性，并找出最关键的节点的仿真程序。(In MATLAB, the nodes / edges of the established network are attacked randomly and intentionally. The invulnerability of the network is measured by the maximum connectivity sub graph and network efficiency, and the simulation program of the most critical node is found.)

The reliable data delivery is a challenging task in Wireless Sensor Networks (WSNs) due to dynamic and unpredictable changing behaviors of nodes. The traditional cryptographic and authentication based schemes can’t be adopted due to their associated cost and incapability to counter nodes misbehavior attacks. Recently, trust based solutions have proved to be more effective to address nodes’ misbehavior attacks. Apart isolating misbehaving nodes, the existing trust based schemes lacks the capability to minimize link failure notifications due to transient transmission disruption which consequently give rise to frequent route breakages thereby undermining throughput and route stability. Moreover, the existing solutions give rise to high energy consumption and control overhead in pursuit of trust estimation and network-wide dissemination which not only adds to network congestion but also undermines network lifetime. In this paper, we present a Trust and Energy aware Routing Protocol (TERP) that

有关PPCA的计算程序，具体可见内部文件及说明，程序比较经典，很值得参考！(the PPCA the calculation procedures, visible and internal documents show that classical procedures that it is worthy reference!)

Side impact accidents against a tree or pole remainthe most dangerous accident scenarios in rally cars. Statistical data shows that 52 of the fatalities between 2004 and 2009 concern crashes against a rigid pole by the track sides, whilst among those more than 60 were side impacts. Despite the present scientific efforts, rallying cars side impacts are still among the least understood primarily due to limited space between the occupant and door sill, evolving safety regulations and vehicle dynamics.
