Goal

Performance metrics

Compared with

1

Energy efficient thermal and power aware routing (ETPA) [19]

To reduce the node’s temperature and to prevent the hotspot formation

Packet hop count, packet delivery ratio, packet delay, average temperature rise of nodes in the network, scalability, depletion time of the first node mobility

PRPLC

2

Prediction based secure and reliable routing framework (PSR) [20]

To provide secure and reliable routing from various data attacks

Packet dropping rate, authentication cost

Backbone protocol

3

Opportunistic routing [21]

To increase the network lifetime from the motion of body parts

Average energy consumption per bit

Single hop, multi hop

4

Distance vector routing with postural link costs (DVRPLC) [22]

To decrease end to end delay

Average delay, packet delivery ratio, packet hop count

Probabilistic protocol (PROPHET), opportunistic protocol, UTILITY

5

On-body store and flood routing (OBSFR) [18]

To provide better routing delay and hop count

End-to-end packet delay (PD), number of transmissions per packet (NTPP), packet delivery ratio (PDR)

PROPHET, on-body store and flood routing (OBSFR)

6

Probabilistic routing with postural link costs (PRPLC) [23]

To reduce end to end delay

Average delay, packet delivery ratio

PROPHET, OBSFR
