Properties of static and mobile unreliable networks and their effects on combating malicious objects.

摘要

Wireless sensor networks or WSNs continually become more common in todays world. They are able to give us a constant view into the world as they gather information and make this information more readily available. The information these networks gather and contain is valuable and protecting it is of great importance. Today more and more devices are becoming wireless and mobile. This is allowing for very diverse networks to be created and they are constantly changing. Nodes in these networks are either moving to different positions or going offline which constantly changes the overall layout of the network. With this increasing connectivity of today's devices this opens the door for possibility for these types of networks to become targets by malicious objects designed to bring harm to the network. Many unreliable networks already face many problems such as having to optimize battery life and being deployed in areas where they can be damaged. A malicious object in this type of network has the power to destroy data and deplete the networks limited resources such as bandwidth and power. Removal of these malicious objects can also have a negative effect on these limited resources. We must find a way to remove these malicious objects in a way that minimizes loss to the network. In this paper we will look at the information survival threshold of these types of networks. Certain controllable parameters exist that directly impact the survival rate of all data in the network. We will combine this with the addition our own self-replicating objects to the network designed to neutralize their malicious counterparts. We will examine these information survival threshold parameters along with specific parameters available to the network. We shall see how these parameters affect overall survival of data in the network and their impact on our own good data.
