Need matlab implementation of this paper within this month. Paper says, sensor nodes deplyoment in different power levels with master node communicating with all other regular nodes. Regular nodes should be deployed in power level fashion.
Abstractâ€”Key management is considered to be the prerequisite
for secure communication in WSNs. However, many of those key
management schemes normally either require the predeployment
knowledge to generate keys, which is unrealistic,
especially in large scale sensor networks, or consume a large
amount of energy. In this paper, we present a new key
management scheme named Energy-efficient Location-dependent
Key Management scheme (ELKM). ELKM generates keys for
each node based on their relative locations. Based on loose time
synchronization, ELKM reduces energy consumption
significantly on the total size of transmitted message comparing
with previous works. The performance analysis shows that
ELKM guarantees high security level and good network
connectivity. Simulation results demonstrate that ELKM
consumes less energy compared with LDK.
