Data propagation in wireless sensor networks is usually performed as a multihop process. To deliver a single message, the resources of many sensor nodes are used and a lot of ener...
—As mobile nodes roam in a wireless network, they continuously associate with different access points and perform handoff operations. However, these handoffs can potentially incu...
