Literature Review Title: A Survey on Evaluation Schemes for Routing Misbehaviors in Manet 
Chapter Title:  Secure incentive protocol 
1. Abstract of Cited Paper (BIB001):  Security in mobile ad hoc networks (MANETs) has received intensive attention recently, whereas the issue of selfish nodes, which may refuse to forward packets for others to save their own resources, is not well addressed yet. This kind of noncooperative action would cause a severe problem that is more likely in MANETs compared to their wired counterpart To cope with this problem, we propose SIP: a secure incentive protocol to stimulate cooperation among those possible selfish nodes. The most attractive feature of SIP is that it does not rely on any predeployed infrastructure and provides highly secure incentives for selfish nodes to be cooperative in packet forwarding with low overhead and implementation complexity. 
2. Abstract of Cited Paper (BIB002):  The proper functioning of mobile ad hoc networks depends on the hypothesis that each individual node is ready to forward packets for others. This common assumption, however, might be undermined by the existence of selfish users who are reluctant to act as packet relays in order to save their own resources. Such non-cooperative behavior would cause the sharp degradation of network throughput. To address this problem, we propose a credit-based Secure Incentive Protocol (SIP) to stimulate cooperation among mobile nodes with individual interests. SIP can be implemented in a fully distributed way and does not require any pre-deployed infrastructure. In addition, SIP is immune to a wide range of attacks and is of low communication overhead by using a Bloom filter. Detailed simulation studies have confirmed the efficacy and efficiency of SIP.

Literature Review:
Secure Incentive protocol charges or rewards nodes for the service they receive or provide. SIP assumes that each mobile node (MN) has a tamper-proof security module such as SIM cards in GSM networks, which deals with security related functions and each intermediate node (IN) puts non forged stamps on the forwarded packets as a proof of forwarding BIB003 . BIB001 Secure Incentive Protocol, (SIP) uses "credits" as the incentives to stimulate packet forwarding. SIP is implemented in the smartcard of each MN. SIP is session-based and mainly consists of three phases. BIB002 During the first Session initialization phase, a session initiator(SI) negotiates session keys and other information with a session responder (SR) and INs between them. And each IN puts a non-forged stamp on each data packet forwarded and SI/SR collect those stamps for later rewarding use in the next Data forwarding phase. The final phase is Rewarding phase, in which each IN is awarded a certain number of credits based on the number of forwarded packets.
