... trafficloadina uniform network topology. on/off and choose the source-destination pair randomly. The destination-based routing protocol also increases RREQ broadcast times and increases the packets waiting ... The work in [4, 13] proposes new routing metrics considering the link quality dynamics. MiRii proposed in [5] further considers the intra-/interflow interferences in multi-interfa...

... away the packet from the network. In addition, to avoid in nitely looping the same route, packets wandering in a network can maintain a table which keeps track of sensor nodes that the packets ... resulting in the high average temperature. Instead, since our proposed LTRT determines a route to the destination before starting sending packets, it is impossible for packets to roam in...
