A NEW ENHANCED VERSION OF VLEACH PROTOCOL USING A SMART PATH SELECTION
Keywords:WSN, VLEACH, energy efficiency, CH
Wireless technology becomes a fast developed research field in order to respond to our needs.
It has various applications such as health care, emergency situations, industrial applications and home
automation. It has several challenges like security and quality of service. Sensor node has a limited energy
related to its tiny battery. Hence, energy efficiency is considered as an important challenge in Wireless
Sensor Networks (WSNs). This paper aims at describing the various routing categories and the different
efficient routing protocols. Along with this, a new enhanced version of the VLEACH protocol based on
selecting the routing path efficiently is also proposed in this paper. The efficient selection process is based on
electing the Cluster Heads (CHs) and the Vice-CH according to the highest residual energy. In addition, it
uses a cooperative routing between the CHs and Vice-CHs in order to reduce the network energy
consumption. Implementation of Basic VLEACH and Proposed VLEACH is done using NS-2 Simulator.
Simulation results show that the new scheme is more efficient than the original VLEACH protocol. This
protocol will increase the lifetime of sensor networks. So the proposed work can be applied in various WSNs
which are deployed in remote areas and recharging of sensor nodes is an issue.
