MN603 Wireless Networks and Security Page#2 of 4 Prepared by: Dr Nazmus Shaker Nafi Moderated by: Dr Sanjeeb Shrestha March, 2020 Part A Assignment Description Routing can optimize network performance such as delivery ratio, delivery delay, and overhead. In other words, routing determines the sequence of transmitting nodes and the number of packets transmitted by each node. Transmitting nodes and the number of their transmissions influence the generated interference. Routing in wireless sensor networks (WSN) is very challenging due to the inherent characteristics that distinguish these networks from other wireless networks like mobile ad hoc networks or cellular networks. Routing protocols in WSN might differ depending on the application and network architecture. In this assignment, students will investigate on two clustering based protocols, LowEnergy Adaptive Clustering Hierarchy (LEACH) and Power-Efficient GAthering in Sensor Information System (PEGASIS) in Wirelessnetworks. LEACH and PEGASIS are clustering based protocol to collected data from wireless network. The students are required to submit a report including technical details on  Routing mechanism  How these protocols can be used to reduce energy consumption  Advantages and limitations of using these protocols in WSNs  Part B In part B Students are required to continue their investigation on both routing protocol and submit a report covering following aspects of these routing protocols: 1) Highlight Security issues of the routing protocols 2) Discuss the attacks that may happen while operating on these routing protocols 3) How to countermeasure the attacks discussed in 2? 4) Comparative analysis on performance of the routing protocols.

Introduction
As the time is crossing, wireless sensor networks are becoming more important for us. There are few applications which ask for quick data transfer that too with minimum possible interruption. This report is to understand the protocols used for wireless sensor networks. There are many different types of protocols which can be used for WSN, but in this report I have covered LEACH and PEGSIS protocols. These protocols have their own advantages and disadvantages also. There are several types of attacks which occurs on WSN. I have also covered few of them and their counterattacks. Lastly, I have concluded about the protocols and their features. 
Motivation
Wireless sensor networks have become that part of our working models which can’t be replaced. All of us want a network which is most secured and have maximum speed. Rest is dependent on the application desires that which features are more important. To establish a network, it is very important to have complete information about the routing protocols and they should be appropriate for the requirement of the usages. This report will help the reader to understand the features and usages of the protocols and how the attacks on them can be controlled. 
Routing Protocols
A routing protocol can be defined as a process which helps to select a better path for the data or information to be transferred from the source system to destination. The process finds multiple hurdles while selecting the route. The selection of route depends on the type of network, channel characteristics and the performance metrics.
LEACH
This is one of the routing protocols for WSN. It stands for Low Energy Adaptive Clustering Hierarchy. It is considered as a hierarchal protocol which provides high network lifetime and more power consumption (Gill, R. K., Chawla, P., & Sachdeva, M.). It works on the data aggregation. It is based on the cluster approach in which we send the data to the base station. In this protocol, we divide the whole network into clusters and out of them one cluster is chosen as the head. The job of the head cluster is to collect all the information and forward it to the base station. The selection of the cluster head depends on the threshold value. The cluster chooses their number as 0 or 1. This number is then compared with the threshold value and the head must have value less than threshold value. The cluster which satisfies this condition becomes the cluster head else treated as ordinary node. 
The following are the advantages of LEACH routing protocol.
1. The chosen cluster head helps in aggregating the whole data. This results in the reduction of traffic in the whole network. 
2. It also saves the energy because of the single hop routing from nodes to the cluster head. 
3. The lifetime of the WSN is increased. 
4. We do not need any location information about the nodes to create the cluster.
But as we all know all technologies which gives a long list of advantages comes with disadvantages also. Here are the disadvantages of LEACH.
1) It does not provide the number of cluster heads present in the network. 
2) If the cluster dies, then the cluster becomes useless and the data which was gathered by the nodes would never reach its destination.
3) Uneven distribution of the clusters. This results in more energy consumption and huge impact on the performance of the entire network. 
PEGSIS
It stands for power efficient gathering information system. It is based on the chain approach and greedy algorithm. The nodes present in the network organize themselves in the form of chain or implements the greedy algorithm (Kulkarni, A. N., & Tavildar, A. S). If any node dies between the process then the chain rebuilds itself to bypass the dead node. One node is assigned as the leader and it will transfer the data to the base station. The aim of this protocol is the receive and transfer the data to and from the nearest neighbour and returns back to the base station as the leader.
