Comparison of related protocols.

Protocols	Parameters	Methodology	Energy conservation	Reliability	Shortcomings
M-ATTEMPT	Hop count and residual energy	Linear programming model	√		Retransmitted power causes energy consumption
iM-SIMPLE	Distance and residual energy	Cost function	√		Not suitable for emergency applications
BEC	Residual energy	Cost function	√		Selected forwarder nodes consume much energy
EERDT	Residual energy and initial energy	Cost efficient function	√		Network adaptability
M-TSIMPLE	Distance and residual energy	Network flow tree structure and cost function	√		Mobility causes unstable link connection
ELA-W	Residual energy, link efficiency, distance, and hop count	Path cost model	√	√	Not suitable for different data types of transfer
ELA-RP	Remaining node energy, link quality	Score function	√	√	Unconsidered reliability
TCBR	Residual energy, link expiration time, and received signal strength	Fuzzy-based trust inference model	√	√	Algorithm increases computing time
ERP	Residual energy and link quality	Score function	√	√	Not suitable for different scenarios
