Wireless sensor networks are highly prone to faults and errors due to their restrictive capabilities and limited resources. In this paper, some of the challenges facing the wireless sensor networks such as security, routing, computing capability, and battery power, will be discussed. The authors will focus on both security and authentication protocols in attempting to provide a security solution against known malicious attacks. Furthermore, utilizing the existing security protocols in wireless sensor networks has led one to propose a framework that incorporates authentication and encryption techniques in accordance with mobile agent technology in a way that reduces the energy consumption in such low power wireless sensor networks.
