PERFORMANCE EVALUATION OF LEACH & LEACH-C
ROUTING PROTOCOLS IN WIRELESS SENSOR
NETWORKS

ABSTRACT


Wireless Sensor network is a multitude technology. It. due to its dynamic services and
wide range ot- applicability, has adjusted itself in very vast areas of interests, such as
continuous surveillance, handy use in medical field and home automation: due to these
features. WSN has become one of the most attractive area for researchers in the last few
years. It is composed of tiny sensing devices, called motes, which sense a phenomenon
according to a pre-defined mechanism. These motes have very limited capabilities in
respects Of energy and computational power. To efficiently utilize the available
Resources to a sensor node in a WSN, many researchers have proposed and developed
many energy efficient routing protocols. But in spite of all those developments, there are
still very much of limitations. Among all those limitations, energy efficient utilization is
on top in the priority solution list in this area. This thesis simulates LEACH and
LEACH-C protocols to identify the factors which inefficiently exhaust the energy of the
TO enjoy the distributiveness and self-organization of the network in LEACH protocol
rather than the centralized approach of LEACH-C protocol, this study concludes that if
fair cluster formation mechanism is introduced in addition to relying on an energy
efficient NIAC Layer protocol, the performance of LEACH protocol can be further
improved. Moreover, both the protocols provide better support of Real-time data (UDP
flow) than Non Real- Time data (TCP flow).
