"A Survey on Reliable Data Transmission in Wireless Sensor Networks"

Mr. Quanbin Chen


Abstract:

Unlike other networks, reliable data transmission is not a binary logic in
wire-less sensor networks, since guaranteed reliability is expensive to be
implemented. Based on the packet content, data transmission services of
different reliability levels should be supplied discriminatively.
Moreover, rather than the transport layer providing the end-to-end
reliability services, reliability schemes in wireless sensor networks
reside in MAC module, routing module as well as the application module,
all with the first design con-sideration-energy efficiency. In this paper,
we summarize the pervious work according to reliable broadcast and
reliable unicast; discuss the reliability techniques in different modules;
and point out some future directions.
