Recent advances in wireless communications and electronics have helped to
develop sensor nodes which are low-cost, low-power, multifunctional, small in size
and communicate in short distances. These tiny sensor nodes, which consist of
sensing, data processing, and communicating components, leverage the idea of
sensor networks. Ad hoc sensor network is a multihop network made of hundreds
of sensor nodes.
This Paper presents a proposed secure and energy efficient decentralized key
management protocol. The proposed protocol combines three schemes; key
establishment, key update and new node addition scheme. The energy consumption
of the proposed key management is analyzed and compared with those of the
formal protocols. The analysis shows an advantage in term of energy consumption
over the previous work.
