The Cluster Head is selected on the basis of maximum number of nodes connected, thus several sensor nodes cannot reach any CH, even though they are in the transmission range. These nodes are called the isolated nodes. To solve this problem, the proposed a sub_cluster protocol, its role is to reduce the sensor nodes which do not belong the cluster. The major novel contribution of the proposed work is the sub_cluster protocol which provides coverage of the whole network with a minimum number of isolated nodes and has a very high connectivity rates. The sub_cluster protocol allows firstly with great cluster can be grouped many sub_cluster protocol connected to major CH, each sub_cluster protocol, can be connected of the maximum nodes non CH.

In WSN, the use of routing protocols designed for ad hoc networks Traditional is inappropriate. This is due to the characteristics by which to distinguish the two types of networks, hence the need to improve or develop new specific routing protocols for WSN.

LEACH is considered as the first hierarchical routing protocol. It is also one of the most popular hierarchical routing algorithms for WSN, proposed as part of the project. It combines the efficiency in energy consumption and quality of access to the media, and based on the division into groups, with a view to allow the use of the concept of data aggregation for better performance in lifetime of terms.

Hybrid, Energy-Efficient Distributed Clustering (HEED) (Younis et al., 2004) extends the basic scheme of LEACH by using residual energy and node degree or density as a metric for luster selection to achieve power balancing. It operates in multi-hop networks, using an adaptive transmission power in the inter-clustering communication

In Adaptive Periodic Threshold-sensitive Energy Efficient sensor Network protocol (APTEEN) (Manjeshwar et al., 2002), the cluster-heads broadcasts the following parameters Attributes, Thresholds, Schedule& Count Time. Once a node senses a value beyond hard threshold (HT), it transmits data only when the value of that attributes changes by an amount equal to or greater than the soft threshold (ST). If a node does not send data for a time period equal to the count time, it is forced to sense and retransmit the data.

Advantages APTEEN include its suitability for time critical sensing applications. At every cluster change time, fresh parameters are broadcast and so, the user can change them as required.
