摘要：A sensor in order to communicate with another sensor within the sensor network needs to find out the sensor which is adjacent to it. So within the network, a sensor needs to find out its adjacent sensor and communicate with it. In order to commu-nicate it needs to maintain some authentication information. If the sensors are mobile then it is difficult to expect the adjacent sensors. So each sensor has to maintain the information of all other sensors. This increases the non-data overhead. So, if there are ‘n’ sensors within the network then each sensor has to maintain the keys of the remaining ‘n-1’ sensors (which is ‘n*(n-1)’) for the network. So through our project we reduce the keys information from ‘n-1’ to a maximum of ‘(n+1)/2’. This could be achieved with the help of a new concept called ‘Key Sender’.
