Inter Cluster Group Management in Wireless Sensor Networks

Wireless Sensor Networks (WSNs), an emerging large-scale
network system can be embedded for any application. The designers of
wireless sensor network have to consider the quality of service agreements
from a user perspective. The WSN is very rapid in dynamic changing
topology and has less energy, computing and communication resources.
The network design has to fulfill the QoS parameters like reliability,
timeliness and lifetime of the network. In wireless sensor network, when
two nodes transmit messages through a common visible node and collision
occurs between these nodes is refers to as Hidden Node Problem. Many
researchers have reviewed the Hidden node problem affecting the
throughput and lifetime of the network. This paper proposed Inter-Cluster
Grouping Mechanism (ICGM) to handles the problem of inter-cluster
grouping and hidden node for the improvement of Quality of Service (QoS)
factors in WSN. The performance of WSN degrades due to the occurrence
of inter-cluster interference caused by different grouping mechanism as
imposed in different clusters. The proposed mechanism (ICGM) overcome
the problem of inter-cluster interference and increases the QoS in WSNs.
