ABSTRACT: As a representative of chain-based protocol in Wireless Sensor
Networks (WSNs), EEPB is an elegant solution on energy efficiency. However, in the
latter part of the operation of the network, there is still a big problem: reserving
energy of the node frequently presents the incapacity of directly communicating
with the base station, at the same time capacity of data acquisition and transmission
as normal nodes. If these nodes were selected as LEADER nodes, that will accelerate
the death process and unevenness of energy consumption distribution among nodes.This paper proposed a chain
routing algorithm based ontraffic prediction model (CRTP).The novel algorithmdesigns a threshold judgment method through introducing the traffic prediction
model in the process of election of LEADER node. The process can be dynamically
adjusted according to the flow forecasting. Therefore, this algorithm lets the energy
consumption tend-ing to keep at same level. Simulation results show that CRTP has superior
performance over EEPB in terms of balanced network energy consumption and the prolonged
network life.
