In the area of wireless sensor networks, achieving minimum energy consumption is a very important research issue. A number of energy efficient protocols have been proposed, mostly ...
When asymmetric cryptography techniques are used in wireless networks, the public keys of the nodes need to be widely available and signed by a Certificate Authority (CA). However,...
: Most wireless ad hoc sensor networks are susceptible to routing level attacks, in which an adversary masquerades as a legitimate node to convince neighbouring nodes that it is th...
