CAMF: Context-Aware Message Forwarding In Selfish Mobile Social Networks

ABSTRACT:

Nodes may exhibit selfish behaviors in mobile social networks (MSN) selfish nodes refuse to forward messages for all or some nodes in a network to conserve limited resources. Previous work mainly focuses on promoting selfish nodes transmit messages for others. In this paper, we consider selfishness from a different viewpoint; we regard selfishness as a basic requirement of systems and allow nodes to behave selfish behaviors. However, selfishness has a profound influence on routing performance. To achieve a good routing performance when node selfishness is considered, we first put forward a stateless approach which does not need collecting and storing state information to measure the similarity of nodes, and then evaluate the forwarding capability of nodes by combining the acquired similarity with node selfishness. We then quantify the receiving capability of nodes based on their available buffer size and energy. Incorporating forwarding and receiving capability, we present a forwarding set mechanism, which formulates the forwarding set optimization problem as a multiple knapsack problem to maximize the forwarding profit. Consequently, we take all the results above into our context-aware message forwarding design. Extensive trace-driven simulations show that our proposed algorithm achieves good routing performance with low transmission cost and resource consumption in selfish MSN.

AIM

The aims of this paper achieve a good routing performance when node selfishness is considered we first put forward a stateless approach which does not need collecting and storing state information to measure the similarity of nodes, and then evaluate the forwarding capability of nodes by combining the acquired similarity with node selfishness.

SCOPE

 The Scope of this project is Extensive trace-driven simulations show that our proposed algorithm achieves good routing performance with low transmission cost and resource consumption in selfish MSN.

EXISTING SYSTEM

In the real world, some or all individuals may exhibit various degrees of selfishness when forwarding messages, in particular when nodes are constrained with energy and storage space, e.g., a node may refuse to accept and store messages for others in order to conserve limited buffer

and power resources. In general, node’s selfish behaviors are considered from two aspects: individual and social selfishness. For individual selfishness, a node exhibits the same forwarding willingness to any others. While, for social selfishness, nodes are more interested in receiving and forwarding messages for the nodes in the same community, but are less interested in receiving and forwarding messages for the nodes outside their communities.

DISADVANTAGES:

1.  Selfish  nodes refuse to forward messages for all or some nodes in a network to conserve limited resources
2. Selfishness  has a profound influence on routing performance

PROPOSED SYSTEM

In this paper, to be consider node selfishness from a different perspective; we regard node selfishness as a basic requirement of applications or systems, and utilize the selfish characteristic of nodes to reduce resource consumption and extend the network lifetime. Nevertheless, it is difficult to achieve an acceptable routing performance when selfishness is considered. Because selfish nodes may refuse to accept or forward messages from others. Thus, our goal is to achieve high delivery performance with a low cost when nodes are allowed to exhibit selfish behaviors develop a context-aware message forwarding algorithm (CAMF), which exploits the context information to quantify the forwarding and receiving capability of nodes and to determine the forwarding set.

ADVANTAGES

1. CAMF achieves good routing performance with low transmission cost when nodes are allowed to exhibit selfish behaviors.
2. To design incentive schemes to stimulate selfish nodes to forward messages for other nodes to achieve a good routing performance.
