  1. 1. COOPERATIVE LOAD BALANCING AND DYNAMIC CHANNEL ALLOCATION FOR CLUSTER-BASED MOBILE AD HOC NETWORKS Presented by IIS TECHNOLOGIES No: 40, C-Block,First Floor,HIET Campus, North Parade Road,St.Thomas Mount, Chennai, Tamil Nadu 600016.

  2. 2. Abstract • Mobile ad hoc networks (MANETs) are becoming increasingly common, and typical network loads considered for MANETs are increasing as applications evolve. • This, in turn, increases the importance of bandwidth efficiency while maintaining tight requirements on energy consumption delay and jitter. • Coordinated channel access protocols have been shown to be well suited for highly loaded MANETs under uniform load distributions. • However, these protocols are in general not as well suited for non-uniform load distributions as uncoordinated channel access protocols due to the lack of on-demand dynamic channel allocation mechanisms that exist in infrastructure based coordinated protocols. • In this project, we present a lightweight dynamic channel allocation mechanism and a cooperative load balancing strategy that are applicable to cluster based MANETs to address this problem. • We present protocols that utilize these mechanisms to improve performance in terms of throughput, energy consumption and inter-packet delay variation (IPDV). www.iistechnologies.in Ph: 9952077540
  3. 3. Existing System • A distributed dynamic channel allocation algorithm with no optimality guarantees for a network with a fixed a-priori control channel assignment. • Alternatively, there are various game-theoretic approaches to the channel allocation problem in ad hoc wireless networks. • Multichannel model the channel allocation problem in multi-hop ad hoc wireless networks as a static cooperative game, in which some players collaborate to achieve a high data rate. • In multi-hop wireless networks, CSMA techniques enable the same radio resources to be used in distinct locations, leading to increased bandwidth efficiencies at the cost of possible collisions due to the hidden terminal problem. • Different channel reservation techniques are used to tackle the hidden terminal problem. Karn use an RTS/ CTS packet exchange mechanism before the transmission of the data packet. • 802.11 distributed coordination function (DCF) uses a similar mechanism. www.iistechnologies.in Ph: 9952077540
  4. 4. Disadvantages www.iistechnologies.in Ph: 9952077540 • Existing approaches are not scalable • They not cover group communication
  5. 5. Proposed System www.iistechnologies.in Ph: 9952077540 • In this project we propose two algorithms to cope with the non-uniform load distributions in MANETs: a light weight distributed dynamic channel allocation (DCA) algorithm based on spectrum sensing, and a cooperative load balancing algorithm in which nodes select their channel access providers based on the availability of the resources. • We apply these two algorithms for managing non-uniform load distribution in MANETs into an energy efficient real-time coordinated MAC protocol, named MH-TRACE. In MH-TRACE, the channel access is regulated by dynamically selected cluster heads (CHs). • MH-TRACE has been shown to have higher throughput and to be more energy efficient compared to CSMA type protocols. • Although MH-TRACE incorporates spatial reuse, it does not provide any channel borrowing or load balancing mechanisms and thus does not provide optimal support to non-uniform loads.
  6. 6. Advantages • Increase the throughput • Here we use scalable approach • Reduce energy consumption www.iistechnologies.in Ph: 9952077540

  8. 8. Conclusion www.iistechnologies.in Ph: 9952077540 • In this project we have not investigated the effects of upper layers such as the routing layer, and instead focused on the MAC layer capability and local broadcasting service. • Packet routing has a significant impact on the load distribution. • Local link layer broadcasting service is directly used by some routing algorithms such as network flooding. • Moreover, it can be used alongside with network coding and simultaneous transmission techniques for cooperative diversity.
  9. 9. Future Work www.iistechnologies.in Ph: 9952077540 • In general, joint optimization of the MAC and routing layers may enable even more efficient solutions. Investigation of the effects of routing is left as future work.
