Wireless sensor networks (WSN) is tending towards becoming a complete solution in communication
protocols, embedded systems and low-power implementations. However, the resource constraints which
includes, limited communication range, limited energy, limited computing power, limited bandwidth and
the fear of intruders have limited the WSN applications. Since lightweight computational nodes that are
currently being used in WSN pose particular challenge for many security applications, the whole
research therefore, is the investigation of new security techniques and appropriate implementation for
WSN nodes, including various trade-offs such as implementation complexity, power dissipation, security
flexibility and scalability. The goal of this research is to develop a network that has efficient and flexible
key distribution scheme secured enough to prevent algorithmic complexity and denial of service attacks
as well as the network able to conserve energy. A review of previous research to date in the area of
security for WSNs was carried out and proposals are made based on security schemes that gather data in
an energy-efficient mechanism through secured pre-allocation of keys, faster clustering routing
algorithm and dynamic based rekeying implementation.
