Summary of existing BSN routing protocols.

Protocol	Content		Resolved Issues
FPSS	Choosing path intelligently among nodes based on heuristic self-adaptive algorithm in energy constrained on-body network.		Energy balance
PRPLC	Forwarding packets to proper neighbors by prediction of postural trend based on link likelihood fact.		Topological partition
TARA	Establishing route to detour around hotspots area using a withdrawal strategy.		Minimizing the thermal effects of Implanted biosensor
LTR		Always choosing neighboring node with the lowest temperature as next stop.
ALTR	Choosing next stop by both the lowest temperature node and the shortest hop count.		Implanted biosensor
LTRT	Choosing the shortest path based on a Dijkstra algorithm with the weight of temperature.		Implanted biosensor
