摘要：Traditional routing protocols are quite vulnerable
under the attacks from both external and internal attackers. In
this work, we examine the impact of a wide variety of attacks
in malicious wireless sensor networks scenario. An Efficient and
Secure Geographic Routing protocol ESGR is proposed to exploit
the geographic location, cryptography mechanisms, and broadcast
nature of the wireless channel. ESGR utilizes the geographic
leashes and the TESLA scheme to provide resistance against
the Sybil attack and wormhole attack. Meanwhile, it employs a
distributed trust model and the packets opportunistic forwarding
to prevent black hole and gray hole attacks. We demonstrate the
results through analysis and simulations that ESGR effectively
mitigates a specific variety of attacks and ensures high packet
delivery rate in malicious sensor network environment.
