An improved routing protocol based on OVSF code transmission in wireless sensor networks
نویسندگان
چکیده
LEACH protocol is a low energy consumption adaptive clustering routing protocol which is firstly proposed by MIT scholars. Considering the disadvantages of the TDMA mechanism that used in LEACH, such as long time delay and high energy consumption, an improved routing protocol based on OVSF code transmission is proposed. Facilitated by its orthogonality and incoherence, the transmission can be realized based on the demands of the node, but not the time slot, during which it has to transmit data to the cluster heads. The simulation results show that the improved routing protocol greatly reduces delay and energy consumption.
