The low cost, ease of deployment has exposed WSNs an attractive choice for numerous applications,like environmental monitoring applications , security applications, real time tracking, and so on.
But in reality, these networks are operated on batte
ry with limitations in their computation capabilities, memory, bandwidth ,so they called networks with resource constrained nature, and this impels various challenges in its design and its performance.
Limited battery capacity of sensor nodes makes energy efficiency a major and challenge problem in wireless sensor networks. Thus, the routing protocols for wireless sensor networks must be energy efficient in order to maximize the network lifetime.
In this paper we simulated LEACH,SEP,DEEC,TEEN routing protocols and evaluated their performance by comparing with DT routing protocol in Homogeneous and Heterogeneous Wireless Sensor Networks on MATLAB.
In this PAPER, we perform a study and extensive comparative between
the well-known link quality estimators and CTP, a tree-based routing
protocol provided by TinyOS for different network topology and simulate
it using TOSSIM simulator to evaluate
the performance of these
estimators.
Mobile Wireless Sensor Network (MWSN) is an emerging technology for attraction of
researchers with its research advantage and various application domains. Due to limited
resources of sensor nodes such as transmission power, communication capability
and
size of memory, data aggregation algorithms are the most practical technique that reduces
large amount of transmission in this network. Security is an important criterion to be
considered because, wireless sensor nodes are deployed in a remote or hostile
environment area that is prone to attacks easily. Therefore, security are essential issue
for MWSN to protect information against attacks.
In this research, we offered an algorithm of secure data aggregation in MWSN based on
pair-wise keys technology and hash function. We studied important parameters such as
execution time, end-to-end delay and number of storied keys. Results showed that
Mobile wireless networks consist of a set of cooperative and
mobile nodes, each node can move randomly at a specific speed
in all directions without any control of a central manager. This type
of networks has become a hot research topic due to its
military
application and suitability for emergencies and natural disasters.
Due to the lack of fixed infrastructure, the routing process
becomes the major problem in this type of networks, where the
responsibility of routing is transferred to each node. Over the last
few years, a number of traditional routing protocols has been
proposed, but these protocols do not support quality of service in
different environments.
Some studies have improved some of these protocols to support
quality of service for specific environments. This research
identifies and analysis some of these improved protocols.
Wireless Sensor Networks (WSNs) are deployed in adversarial environments and
used for critical applications such as battle field surveillance and medical monitoring, then
security weaknesses become a big concern. The severe resource constraints of
WSNs give
rise to the need for resource bound security solutions.
The Implicit Geographic Forwarding Protocol (IGF) is considered stateless, which
means that it does not contain any routing tables and does not depend on the knowledge of
the network topology, or on the presence or absence of the node in WSN. This protocol is
developed to provide a range of mechanisms that increase security in IGF. Thus it keeps
the dynamic connectivity features and provides effective defenses against potential attacks.
These mechanisms supported the security against several attacks as Black hole, Sybil and
Retransmission attacks, but the problem was the inability of mechanisms to deal with
physical attack.
This research deals with a detailed study of the SIGF-2 protocol and proposes an
improvement for it, in which we use the concept of deployment knowledge from random
key pool algorithm of keys management to defend against physical attack . The evaluation
of simulation results, with different parameters, proved that our proposal had improved the
studied protocol.
