Mobil Tasarsız Ağlar için Acil Durum ve Kurtarma Senaryolarına Yönelik bir Protokol: E-AODV

Mobil tasarsız ağlar (MTA), önceden tanımlı bir sabit altyapı olmadan birbirleriyle iletişim kuran mobil cihazlardan oluşmaktadır. Bu özelliğinden dolayı mobil tasarsız ağların acil durumlarda kullanılması önemli faydalar sağlamaktadır. Dinamik ve değişken bağlantılardan dolayı acil durum ve kurtarma senaryolarında veri iletiminde uçtan uca gecikme, bant genişliğinde tıkanıklık, paket iletiminde azalma gibi çeşitli aksaklıklar meydana gelmektedir. Bu çalışmada, Ad hoc On-Demand Distance Vector (AODV) protokolünün kuyruk yapısı değiştirilerek, TCP paketlerine öncelik veren Emergency AODV (E-AODV) protokolü geliştirilmiştir. E-AODV ile verilerin daha düşük uçtan uca gecikme süresinde iletilmesinin yanı sıra paket dağıtım oranının ve throughput değerlerinin arttırılması amaçlanmıştır. Önerilen protokolün başarımı iki farklı senaryo kullanılarak sınanmış ve sonuçlar literatürdeki benzer çalışmalarla kıyaslanmıştır. E-AODV, uçtan uca gecikme, paket dağıtım oranını ve throughput değerleri açısından her iki senaryoda da daha başarılı sonuçlar vermiştir.

E-AODV: a Protocol Devoted to Emergency and Rescue Scenarios for Mobile Adhoc Networks

Mobile ad hoc networks (MANETs) consist of mobile devices that communicate with each other without a predefined fixed infrastructure. Using of MANETs provides significant benefits in emergencies thanks to this feature. Various malfunctions such as end to end delay, bandwidth congestion and, reduction in the packet transmission ratio occur in data transmissions due to dynamic and variable connections in emergency and rescue scenarios. In this study, Emergency Ad hoc On-Demand Distance Vector (E-AODV) protocol, giving priority to TCP packets, was developed by modifying the queue structure of the AODV protocol. It is aimed transmitting data within less end to end delay time along with increasing packet transmission ratio and throughput, through E-AODV. The performance of proposed protocol was investigated on two different scenarios in a simulation environment and compared with similar studies in literature. E-AODV gave more successful results in terms of the packet delivery ratio, end to end delay and, throughput for the both scenarios.
