Description: Wireless Sensor Networks are wireless networks where every nodes recolects surrounding information. WSNs have several aplications such as militar survival, traffic control, building security, scientific research in other planets, etc. This project presents a communication protocol for wireless sensor networks based on the ant colony optimization metaheuristic, which uses artificial ant agents that recolects data from all sensor nodes of the network. Every ants fuzes data from a node and sends it to every other sensor and then to the base station. All ants look for a way to go where there is an energy eficient path.

Description: The sensor networks application domain continues to increase with the need for an
effective security mechanism. The fact that WSN often deal with sensitive data operating in
hostile and unexpected environments, makes the concept of security considered essential.
However, because of limited resources and low computing capacity of a sensor node, the
development of a mechanism that ensures security is a real design challenges.
In this report we have tried to propose a new security mechanism dedicated to WSN. Our
main objective is to secure the process of transferring data to the base station. The proposed
protocol protects transferred data against intruder nodes attacks, using a security
mechanism based on the use of control message MAC (Message Authentication Code) for
authentication. Our protocol performances are evaluated using the simulator NS2.

Description: Wireless Sensor Networks (WSNs) have attracted much attention in recent years. The potential applications of WSNs
are immense. They are used for collecting, storing and sharing sensed data. WSNs have been used for various applica-
tions including habitat monitoring, agriculture, nuclear reactor control, security and tactical surveillance. The WSN
system developed in this paper is for use in precision agriculture applications, where real time data of climatologically
and other environmental properties are sensed and control decisions are taken based on it to modify them. The architec-
ture of a WSN system comprises of a set of sensor nodes and a base station that communicate with each other and
gather local information to make global decisions about the physical environment. The sensor network is based on the
IEEE 802.15.4 standard and two topologies for this application. -Wireless Sensor Networks (WSNs) have attracted much attention in recent years. The potential applications of WSNs

Description: Wireless Sensor Networks (WSN) are becoming popular day by day,
however one of the main issue in WSN is its limited resources. We
have to look to the resources to create Message Authentication Code
(MAC) keeping in mind the feasibility of technique used for the
sensor network at hand. This research work investigates different
cryptographic techniques such as symmetric key cryptography and
asymmetric key cryptography. Furthermore, it compares different
encryption techniques such as stream cipher (RC4), block cipher
(RC2, RC5, RC6 etc) and hashing techniques (MD2, MD4, MD5,
SHA, SHA1 etc). The result of our work provides efficient
techniques for communicating device, by selecting different
comparison matrices i.e. energy consumption, processing time,
memory and expenses that satisfies both the security and restricted
resources in WSN environment to create MAC.

Description: Wireless Embedded Systems (WEBs) has attracted significant interest in recent years, for instance, Wireless Sensor Networks (WSN), have recently been in the limelight for many domains. The characteristics of WEBs have imposed various restrictions on their system designs. Since embedded systems usually are developed by low-cost hardware, one major challenge in the development of many WEBs applications is to provide high-security features with limited resources. In this paper, we propose a novel key establishment scheme, named half-key scheme that based on the well-known random key pre-distribution scheme and DDHV-D deployment
knowledge to provide resource-efficient key management in WEBs with reduced memory space requirements and better security enforcement. The capability of the proposed approach is evaluated by an analytical model and a series of
experiments.

Description: Wireless Sensor Networks (WSN) have recently been in the limelight for many domains. WSN are useful in data collection, event detection or entity tracking applications. The characteristics of sensor networks have imposed various restrictions on their system designs. Since sensor nodes usually are developed by low-cost hardware, one major challenge in the development of many sensor-network applications
is to provide high-security features with limited resources. In this paper, we propose a path generation framework with deadline considerations for real-time query processing.
To meet the deadline, the framework will assign the time budget to the routing path, and then, derive a feasible path with the assigned time budget.

commercial applications based on Ultra Wideband (UWB). It has potentially low complexity,
low cost and an excellent time domain resolution which facilitates location and tracking

Description: Wireless Sensor Networks (WSN) is vulnerable to node capture attacks in which an attacker can capture one or
more sensor nodes and reveal all stored security information which enables him to compromise a part of the
WSN communications. Due to large number of sensor nodes and lack of information about deployment and
hardware capabilities of sensor node, key management in wireless sensor networks has become a complex task.
Limited memory resources and energy constraints are the other issues of key management in WSN. Hence an
efficient key management scheme is necessary which reduces the impact of node capture attacks and consume
less energy. In this study, we develop a cluster based technique for key management in wireless sensor network.

Description: Wireless Sensor Networks (WSN) support data collection and distributed
data processing by means of very small sensing devices that are easy to
tamper and cloning: therefore classical security solutions based on access
control and strong authentication are difficult to deploy. In this paper we
look at the problem of assessing security of node localization.
