Networking along quite of low cost small detector nodes permits users to accurately
monitor a foreign surroundings by showing intelligence combining the information from the
individual nodes .They networks need sturdy wireless communication protocols that square measure
energy economical a nd supply low latency.
In this servey paper, we discover and analyze low -energy adaptive clustering hierarchy (LEACH), a
protocol architecture for micro sensor networks that combines the ideas of energy -efficient clusterbased routing and media access beside application-specific information aggregation to attain
sensible performance in terms of system period of time, latency, and application-perceived quality.
LEACH includes a replacement, distributed cluster formation technique that enables selforganization of huge numbers of nodes, algorithms for adapting clusters and rotating cluster head
positions to equally distribute the energy load among all the nodes, and techniques to modify
distributed signal process to avoid wasting communication resources.
Our results show that LEACH will improve system period of time by AN order of magnitude
compared with all-purpose multi hop approaches.
