Contents Relevance How can energy co-operation help? Problems Incentive Mechanisms Enforcement Mechanisms Looking Forward- Concerns

Relevance – Why this paper? :

Relevance – Why this paper? Increasing 4G users Increasing applications and functions Battery life – A bottleneck for performance

How does energy co-operation work?:

How does energy co-operation work? Relaying nodes Total energy consumed Relative battery power

Challenges: User Willingness:

Challenges: User Willingness No immediate benefit Security and privacy concerns Resource Limitation Selfish Users

Incentive Mechanisms:

Incentive Mechanisms Cost paid by source node Cost paid by destination node Clearance Centre

Enforcement Mechanisms- First hand reputation:

Enforcement Mechanisms- First hand reputation Reputation Value – Incremented and Decremented Identify selfish nodes Penalize selfish nodes Only neighboring nodes

Enforcement Mechanisms- Second hand reputation:

Enforcement Mechanisms- Second hand reputation Reports misbehavior to other nodes Alarm table, trust table and friend list Computationally expensive
