Energy-Efficient Adaptive Geosource Multicast Routing for Wireless Sensor Networks

Table 2

Classification of WSN multicast protocols.

	Tree-based routing	Location-based routing	Source-based routing
Strengths	Small data packet overhead	No distributed routing control overhead, less path encoding and decoding overhead than source-based	No distributed routing control overhead, relatively smaller forwarding computation than location-based
Weaknesses	Stateful, large control overhead (flooding), large memory/storage	Large packet size (location; information of destinations),; large forwarding computation	Large packet size (path), path; encoding and decoding overhead
Examples	MAODV, ADMR, ODMRP, AM-Route, AMRIS	PBM, LGT, GMR, DDM, RDG	DSM
