摘要：Wireless sensor networks are becoming significantly vital to many applications, and they were initiallyused by the military for surveillance purposes. One of the biggest concerns of WSNs is that they are very defenseless tosecurity threats. Due to the fact that these networks are susceptible to hackers; it is possible for one to enter and rendera network. For example, such networks may be hacked into in the military, using the system to attack friendly forces.Leap protocol offers many security benefits to WSNs. However, with much research it became apparent that LEAPonly employs one base station and always assumes that it is trustworthy. It does not consist of defense against hackedor compromised base stations. In this paper, intensive research was undertaken on LEAP protocols, finding out itssecurity drawbacks and limitations. A solution has been proposed in order to overcome the security issues faced inimplementing this protocol whilst employing more than one base station. The performance of the proposed solution hasbeen evaluated and simulated to provide a better network performance.
