Wireless sensor networks are one of the most interesting and challenging research domains of our time. They have a great potential to be deployed in wide critical applications, such as military monitoring, health care as well as civilian applications. The highly sensitive nature of collected information makes security in these special networks a crucial concern. Owing to the hostile nature of their deployment environments, the wireless medium and the constrained nature of resources on the tiny sensor devices used in such networks, security poses more severe challenges compared to the traditional networks. As attacks to any part of the hardware or software may gives significant damages to these networks. Indeed, the development of effective and efficient defense mechanisms to those attacks must be addressed at every stage of the system design. Wireless sensor networks have attracted a wide range of disciplines where close interactions with the physical world are essential. The distributed sensing capabilities and the ease of deployment provided by a wireless communication paradigm make WSNs an important component of our daily lives. Energy conservation emerges as one the most critical aspect in hardware and software related design issues. Also other related main issues include specialized hardware, software and operating system, synchronization, QOS, security, architecture and data collection related aspects with minimum communication and computation costs. This paper provides an overall view of various such issues for the better understanding of this field for the overall benefit of the research community working in this area.
