Wireless Sensor Networks is an emerging technology in the field of communication. Wireless sensor nodes provide real observed data from the different environmental conditions and provide data for monitoring and controlling the systems. WSNs are suitable for various applications such as intelligent surveillances, border security and disaster management by gathering remote data about surroundings either periodically or on demand. The major considerations of WSN are resource scarcity in terms of bandwidth and energy, coverage and route optimality. In WSNs distinct Localization Approaches, Clustering Techniques, Routing protocols are used to minimize the energy requirement, improve the communication effectiveness, and maximize the throughput and efficiency of the network. The significant improvement in the network lifetime is also achieved by using various approaches such as swarm intelligence and bio inspired techniques. In this paper we have discussed the various clustering techniques proposed by the researchers and provide a comparative analysis of them. To develop a novel method to solve the multi objective problem of energy conservation, node localization, optimal coverage and best route identification is our future work.

The Autonomous Mini-robot Soccer Tournament (AMiRoSoT) league that we describe in this article uses small size robots and a small size field to make the league widely accessible for education and research by keeping the entry barrier to the competition low. We describe the motivation for small size soccer robots and the design criteria applied to the formulation of the league's rules. We examine the requirements for the robots capable of playing in the league and discuss possible low cost robot realisations. An analysis of the goal kicking behaviour illustrates the breath and depth, and the educational and research opportunities, of the league.

Combining with the cognition of human skin, a kind of flexible, stretchable large-area electronic device network (electronic skin) have been demonstrated for the detection of deformation and pressure, which allow robots to maneuver within environment safely and effectively. Through the application of soft technology, we potentially reduce the mechanical and algorithmic complexity involved in robot design. In our experiments we used soft materials coating AgNWs and the FFT algorithms to measure pixel pressure. Polydimethylsiloxane (PDMS) has overwhelmingly been used as substrates of E-skin and other stretchable electronics. Arduino is also used in our experiment as a single-board microcontroller, intended to make the application of interactive objects or environments more accessible.

This paper presents a simple four-legged robot platform that can transform a smartphone or tablet into an autonomous walking social robot. Smartphones are already designed to be easy to interact with and to assist humans in everyday activities. They are also equipped with impressive computational resources and powerful sensors. As such they can serve as a powerful controller for a robot. By giving them four legs they have the added abilities to walk about our environments and express themselves using posture and body language. An example of such a four-legged robot is described in this paper along with a preliminary exploration of its capabilities as a social robot. Simple walking and posturing are demonstrated in ways that show how such a robot can better play the role of companion or assistant in the office or home. The platform is designed and built using inexpensive off-the-shelf components and can serve as an affordable development system for students and practitioners who wish to study social robotics.

In order to study and apply the ant foraging theory,this paper introduced the modeling method based on agent to construct the ant colony foraging behavior model. Through constructing many effective ant behavior rules,such as the path selection rules,which was added the function of perceiving information,the reward and punishment rules which could regenerate the pheromone and strengthen the speed and the intelligence of ant routing. Comparing with the existing classic literature,it determined the effectiveness of the model. In order to verify the adaptability of ants foraging behavior model,the model was used to the local path planning of mobile robot. The simulation results show the ants foraging behavior model can quickly determine the optimal path in the complex environment.

Network Mobility (NEMO) is a technology that enables internet services in the public transportation and personal network. To facilitate the internet service in an ongoing vehicle a mobility management protocol shall play a key role. Mobility management is basically responsible for two tasks; node location update of node and service delivery. Present mobility management protocols are incurred with two key issues. First is centralized entity, the central entity provides all intelligence and is responsible for handover process. Therefore, if this entity is fails due to over burden traffic; the whole network is going to suffer. The second issue is related to mobile router; which is frequently moving from one point to another (router visited foreign network). Due to frequently changes in its point of attachment all the running applications will be terminated (session breakup). Therefore; this research work has two objectives. The first objective is to present distributed mobility management architecture to mitigate the central entity issue and the second is to design a handover communication scheme to reduce the long interval, when router changes its point of attachment. Furthermore, an analytical model is developed to analyze the performance of the proposed communication scheme.

Heuristic schemes and algorithms are successfully used for solving optimization problems. A great challenge in large-scale wireless networks is the channel allocation adaptability to dynamic network traffic conditions, which can be formulated as a discrete optimization problem. Several approaches such as genetic algorithms and multi-agent techniques have been applied so far in the literature for solving the resource management problem focusing mainly on network base-stations representation. A very promising intelligent approach known as ant colony optimization (ACO) which constitutes a special form of swarm intelligence has been used for solving routing problems. This approach has been introduced by the authors for improving the channel allocation in large-scale wireless networks, focusing on network procedures as the basic model component and not on network nodes as so far found in the literature. A comprehensive intelligent model architecture based on multi-agent systems technology and ACO for channel allocation in cellular networks is herein analysed and proposed. Moreover, the decision making for channel allocation is presented as well as the network-ant agent communication model. The new methodology for integrating ACO schemes and decision making regarding spectrum reuse in a multi-agent framework, through a novel agent negotiation approach, is the main contribution of this research. Finally, the simulation results show the large-scale wireless network performance improvement in terms of efficient resource management.

Since the 3D structure tensor at each pixel can interpret the local between frames well, it can be used to estimate dense flow. According to the assumptions of brightness constancy, the optical flow estimation can be converted to the calculation the eigenvector of the structure tensor, rather than the complex calculation of linear system. Iterative coarse-to-fine refinement is used to improve the performance. Experimental results show that the proposed algorithm is robust and effective for computing the dense flow.

The rescuing robot can help the workers a lot in searching and rescuing survivors. The design of a tendon-sheath and pneumatic system driven rescue robot is proposed in this dissertation. The robot is designed to solve the insert problem into the ruins and provide some necessary help for the survivor fined by the rescue robot. The introduction of the robot in this paper is divided into two parts: the introduction of mechanical structure and the control system. The robot consists of a searching head, a flexible slender arm, display terminal and a driving unit. The searching head is the most important part of the whole system which is comprised of two pneumatic actuators and a backbone spring. The driving unit is composed of the tendon-sheath, servos, solenoid valves and an air pump, all of these elements are control by MCU. The whole robot system can be packed into a suit case for better carrying.
