Cluster based Location Aware Overlay Multicast over U-Sensor Network
Hyung-Ok Lee, Ji-Seung Nam, Jin-Han Jeon · Advanced Science and Technology Letters · 2013
The need of applications supporting group communication has been gradually increasing both in wired and wireless network environment. In this paper, an overlay multicast protocol over USN(Ubiquitous Sensor Networks), CLAOU, is proposed by using a cluster based approach and a location based approach at the same time. In CLAOU, a cluster is formed based on predefined geometric information to take advantage of the merits come from a cluster based approach and a location based approach.
