up to a mile away. Although this particular security problem is merely

an implementation issue rather than a serious protocol design issue,

some researchers have pointed out several weaknesses in the offi-

cial Bluetooth specifications that may lead to personal information

breaches and device compromise. The Bluetooth specification was

largely based on the assumption that within its limited signal range

of <10 m security was not a significant problem. This turned out to

be a false assumption. Security services in ad hoc networks lead to

new challenges due to the absence of a fixed network infrastructure

in MANET.

Problems such as secured routing, link layer security, and key man-

agement were examined. We introduced two problems ...
