Abstract— A Wireless Sensor Network (WSN) is a collection of
wireless sensor nodes forming a temporary network without
the aid of any established infrastructure or centralized
administration. In such an environment, due to the limited
range of each node’s wireless transmissions, it may be
necessary for one sensor node to ask for the aid of other sensor
nodes in forwarding a packet to its destination, usually the
base station. One important issue when designing wireless
sensor network is the routing protocol that makes the best use
of the severely limited resource presented by WSN, especially
the energy limitation. Another important factor is providing as
much security to the application as possible. In this project, an
energy efficient secure node disjoint multipath routing
protocol for wireless sensor networks is proposed. Here, the
data packets are transmitted in a secure manner by using the
digital signature crypto system. Multipath routing protocols
enhance the lifetime of the wireless sensor networks by
distributing traffic among multiple paths instead of a single
optimal path. The protocol guarantees loop freedom and
disjointness of alternate path. We have compared the
performance of this protocol with an ad hoc on-demand
multipath distance vector routing protocol. To evaluate
performance of proposed method, we have used parameters
packet delivery ratio, energy consumption, routing overhead
and throughput compare to the ad hoc on-demand multipath
distance vector routing .

Abstract — In the recent years, multipath routing
techniques are recognized as an effective approach to
improve QoS in Wireless Sensor Networks (WSNs).
However, in most of the previously proposed protocols
either the effects of inter-path interference are ignored,
or establishing low-interference paths is very costly. In
this paper, we propose a Low-Interference Energyefficient
Multipath ROuting protocol (LIEMRO) for
WSNs. This protocol is mainly designed to improve
packet delivery ratio, lifetime, and latency, through
discovering multiple interference-minimized nodedisjoint
paths between source node and sink node. In
addition, LIEMRO includes a load balancing algorithm
to distribute source node’s traffic over multiple paths
based on the relative quality of each path. Simulation
results show that using LIEMRO in high traffic load
conditions can increase data reception rate and network
lifetime even more than 1.5x compared with single path
routing approach, while end-to-end latency reduces
significantly. Accordingly, LIEMRO is a multipath
solution for event-driven applications in which lifetime,
reliability, and latency are of great importance.
