Mitigating Broadcasting Storm Using Multihead Nomination Clustering in Vehicular Content Centric Networks

Abstract

Vehicles are highly mobile nodes; therefore, they frequently change their topology. To maintain a stable connection with the server in high-speed vehicular networks, the handover process is restarted again to satisfy the content requests. To satisfy the requested content, a vehicular-content-centric network (VCCN) is proposed. The proposed scheme adopts in-network caching instead of destination-based routing to satisfy the requests. In this regard, various routing protocols have been proposed to increase the communication efficiency of VCCN. Despite disruptive communication links due to head vehicle mobility, the vehicles create a broadcasting storm that increases communication delay and packet drop fraction. To address the issues mentioned above in the VCCN, we proposed a multihead nomination clustering scheme. It extends the hello packet header to get the vehicle information from the cluster vehicles. The novel cluster information table (CIT) has been proposed to maintain several nominated head vehicles of a cluster on roadside units (RSUs). In disruptive communication links due to the head vehicle’s mobility, the RSU nominates the new head vehicle using CIT entries, resulting in the elimination of the broadcasting storm effect on disruptive communication links. Finally, the proposed scheme increases the successful communication rate, decreases the communication delay, and ensures a high cache success ratio on an increasing number of vehicles.

Hybrid 802.11p‐cellular architecture for NDN‐based VANET

“…Integrating NDN into VANET is the focus of a growing research effort. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] In this section, we give a brief literature review on NDN-based VANET solutions. A wider survey can be found in.…”

“…In the cluster-based solutions, 10,12,14,16,20,23 vehicles are associated with groups and a cluster head (CH) is selected to control the interest forwarding among cluster members along with other clusters and/or with the infrastructure.…”

“…NDN may represent a valid solution for VANET since the receiver‐based service model of the NDN paradigm fits naturally into the data‐centric VANET applications. Integrating NDN into VANET is the focus of a growing research effort 7–24 . In this section, we give a brief literature review on NDN‐based VANET solutions.…”

“…Another cluster based solution, namely, vehicular‐content centric network (VCCN) was proposed in Siddiqa et al 23 VCCN uses a multihead nomination clustering scheme where the information about multiple cluster head is stored in the RSUs using a Cluster Information Table (CIT) and broadcasted to the vehicles in its proximity to eliminate the broadcast storm problem.…”

Novel Fuzzy Logic Scheme for Push-Based Critical Data Broadcast Mitigation in VNDN

“…In VNDN, vehicles may be consumers, producers, or intermediate vehicles. By design, VNDN supports only a pull-based communication model in which a consumer vehicle creates an interest packet and broadcasts it on the network [ 17 ]. The intermediate vehicles forward the interest packet to other vehicles in the network until it reaches the producer.…”
