摘要：The design and analysis of routing algorithm is an important issue in wireless sensor networks (WSNs). Most traditional geographical routing algorithms cannot achieve good
performance in duty-cycled networks. In this paper, we propose a k-connected overlapping clustering approach with energy awareness, namely, k-OCHE, for routing in WSNs. The basic idea of this
approach is to select a cluster head by energy availability (EA)
status. The k-OCHE scheme adopts a sleep scheduling strategy of
CKN, where neighbors will remain awake to keep it k connected,
so that it can balance energy distributions well. Compared with
traditional routing algorithms, the proposed k-OCHE approach
obtains a balanced load distribution, consequently a longer
network lifetime, and a quicker routing recovery time.
