A framework for securing mobile wireless sensor networks against physical attacks

Security in Wireless Sensor Networks has remained one of the critical and active research realms since last decade. Due to their applications, WSNs are subjective to be deployed in physically hostile environments, where they are vulnerable to various security attacks. The security issue becomes more challenging when sensor nodes are supposed to be mobile. Such types of networks are called Mobile Wireless Sensor Networks. There are various types of security attacks reported in the literature of WSNs in general and mobile WSNs in particular. Among these, one of the less addressed categories of attacks is physical attacks. The Physical attacks are launched by physically accessing and tampering or compromising the sensor nodes. In this paper, we have proposed a generic framework for securing mobile MWSNs against various possible physical attacks.
