Wireless sensor networks: a survey
This paper describes the concept of sensor networks which has been made viable by the convergence of micro-electro-mechanical systems technology, wireless communications and digital electronics. First, the sensing tasks and the potential sensor networks applications are explored, and a review of factors influencing the design of sensor networks is provided. Then, the communication architecture for sensor networks is outlined, and the algorithms and protocols developed for each layer in the literature are explored. Open research issues for the realization of sensor networks are also discussed. 
Wireless sensor networks for habitat monitoring
We provide an in-depth study of applying wireless sensor networks to real-world habitat monitoring. A set of system design requirements are developed that cover the hardware design of the nodes, the design of the sensor network, and the capabilities for remote data access and management. 
Secure routing in wireless sensor networks: attacks and countermeasures
We consider routing security in wireless sensor networks. Many sensor network routing protocols have been proposed, but none of them have been designed with security as a goal. We propose security goals for routing in sensor networks, show how attacks against ad-hoc and peer-to-peer networks can be adapted into powerful attacks against sensor networks, introduce two classes of novel attacks against sensor networks––sinkholes and HELLO floods, and analyze the security of all the major sensor network routing protocols. We describe crippling attacks against all of them and suggest countermeasures and design considerations. This is the first such analysis of secure routing in sensor networks. 
Integrating a Secured Access Control Policy on Wireless Sensor Networks
A new generation of high-scale sensor networks suitable for a range of enterprise application is thriving by current advancements in electronics. In this work, we proposed a mechanism for securing data generation in a wireless sensor network. Wireless sensor networks (WSNs) are networks that provide a virtual layer where the information about the physical world can be accessed by any computational system. WSNs are made up of nodes from a few to several hundreds or even thousands where each node is connected to one or several sensors. The data generated can be easily compromised by an attacker if adequate security measures are not taken. Access and Authorization to the sensory data should be given to authorized users with the right attributes if data integrity and authentication (in a fine-grained manner) should be maintained. The increased security of the proposed system is achieved by the increased in the key size above the existing system. Achieving secure fine-grained access control policy over security challenges like sensor node compromise, accessibility of users to sensor nodes, data privacy, and protection of components on WSNs need a secure system that can precisely specify what the users can access, where and when to access any data at a particular time in the network. 
Performance Analysis of ACO Based Routing Protocols- EMCBR, AntChain, IACR, ACO-EAMRA for Wireless Sensor Networks (WSNs)
This research paper is study of ACO based routing protocols proposed for Wireless Sensor Networks by various researchers. The protocols comprehensively compared via this research paper are: Ant Colony Based Energy Aware Multipath Routing Algorithm for Wireless Sensor Networks (ACO-EAMRA), Improvised Ant Colony Routing (IACR), Efficient Minimum Cost Bandwidth Constrained Routing in Wireless Sensor Networks (EMCBR) and AntChain Protocol. Extensive study on simulations are made on different scenarios and simulation time on Random Way Point Mobility Model for all protocols. The results show that overall IACR is best among all the other protocols to the extent about 30-40% better in terms of Packet Delivery, Energy Efficiency and maintaining overall robustness and scalability of Wireless Sensor Networks.
