HLAODV – A Cross Layer Routing Protocol for Pervasive Heterogeneous Wireless Sensor Networks Based On Location
A pervasive network consists of heterogeneous
devices with different computing, storage, mobility
and connectivity properties working together to solve
real-world problems. The emergence of wireless
sensor networks has enabled new classes of
applications in pervasive world that benefit a large
number of fields. Routing in wireless sensor networks
is a demanding task. This demand has led to a number
of routing protocols which efficiently utilize the
limited resources available at the sensor nodes. Most
of these protocols either support stationary sensor
networks or mobile networks. This paper proposes an
energy efficient routing protocol for heterogeneous
sensor networks with the goal of finding the nearest
base station or sink node. Hence the problem of
routing is reduced to finding the nearest base station
problem in heterogeneous networks. The protocol
HLAODV when compared with popular routing
protocols AODV and DSR is energy efficient. Also
the mathematical model of the proposed system and its
properties are studied.
