Abstract:
Wireless sensor network is a network which contains sensing and routing via nodes mainly called sensorsand it transmits the data
to sink. WSN contains star and mesh topologies or single and multi-hop network. WSN used for monitor physical and
environment condition and deals with many protocols according of various applications. In this paper, we mainly describe
various data prediction techniques toremove redundant data and increase the energy of sensor nodes. Data prediction is one of
the data pre-processing techniques use to predict data at sensor or sink node and aims to remove unnecessary data while
transmission occur from source node to base station. We describe here recent techniques based on data prediction in this survey
which helps to increase energy as well as life of network.

I. INTRODUCTION
Wireless sensor networks (WSN) consist of a large number of
low-cost, spatially distributed, varieties of sensors in
environment for monitoring or sensing purpose. The sensed
data by each sensor node is transmitted to the sink using
single-hop or multi-hop scheme. Each sensor node use the
power supply to sensed and transmit the data and energy of
each node is limited hence it will decrease when more and
more transmission occur by each node.
Wireless sensor networkscan be deployed in a geographical
area for monitoring temperature, pressure ,humidity [1] etc.
WSN are also use the applications such as environmental
monitoring [2], agriculture, medical and process control [3].It
requires sensor nodes to collect data and transmit to the sink at
a specific rate. The data generated by sensornodes usually
contain a large portion of redundant data and transmission of
data may cause unnecessary energy consumption.
Data Reduction techniques are helpful to remove data
redundancy in WSN. It divides in to several parts like data
compression, data prediction, In-network processing [4]and
data aggregation. Data compression is used to reduce the
amount of data sent by sensor nodes. This scheme involves
encoding strategy at sensor node and decoding strategy at sink
if the application doesn’t require the measurements. In-
network processing is useful while data is routed towards the
sink node and use various data aggregation schemes. The goal
is to transmit the sensor data into less voluminous refined data
using the functions like minimum, maximum, average,
entropy etc. But some application require accurate
measurements, in that cases it can degrade accuracy [5].
Data prediction is a technique in which values of data are
predicted at sensor for transmitting or at sink for receiving and
sometimes also called dual prediction in wireless sensor
network. Generally, data prediction is depending on physical
phenomenabeing monitored, prediction models and
algorithms. Data prediction is an efficient approach to reduce
the number of redundant data in sensor network
[6].Dataprediction uses history data sample bysensors to
predict the future data, and not needto transmit the newly
sampled data to the sink. If the difference betweensampled
data and its prediction value iswithin some given error then
only transmission is required. It mainly divided into time-
series approach, stochastic approach and algorithmic
approach. Stochastic approach is used when sensed data value
is considered as a random process by probabilitydensity
function.Moving Average (MA), Least Mean Square (LMS),
Auto-Regressive (AR) or Auto Regressive Moving Average
(ARMA) models are based on time-series approach.
Here, in this survey, we mention various prediction
approaches in WSN like in-network prediction, cluster based
approach, linear prediction, multiple linear prediction and dual
prediction models in order to increase energy of WSN by
removing data redundancy.
II. DATA PREDICTION TECHNIQUES
1. In-network prediction:
In this approach data are collected from sensor nodes and
while transmitting, the values are predicted that called in-
network prediction. It uses regression models. Data collected
by sensor nodes can be considered as temporalseries, where
the time is instant when a givenvalue is collected, sensed data
