Abstract

Selection bias is caused by preferential exclusion of units from the samples and represents a major obstacle to valid causal and statistical inferences; it cannot be removed by randomized experiments and can rarely be detected in either experimental or observational studies. In this paper, we
provide complete graphical and algorithmic conditions for
recovering conditional probabilities from selection biased
data. We also provide graphical conditions for recoverability
when unbiased data is available over a subset of the variables.
Finally, we provide a graphical condition that generalizes
the backdoor criterion and serves to recover causal effects
when the data is collected under preferential selection.

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 .
