In VANETs, Mobility Management is a challenging task because of the fast mobility of the vehicles and small coverage range of 802.11 Access Points (APs). This results in frequent handoffs as vehicles move across a series of adjacent access points. Due to which, the overall throughput reduces and hence results in the interruption of many established(More)
Proactive security mechanism like authentication, confidentiality and non-repudiation are difficult to implement in MANETs. Some additional security necessities are always desirable like cooperation fairness, location confidentiality, data freshness and absence of traffic diversion. Traditional security mechanism (authentication, encryption) provide(More)
BACKGROUND Malaria is a major public health problem in the malaria endemic zones of the world. Various factors influence the prevalence of malaria. This study was conducted to determine the variation in frequency of Plasmodium vivax and Plasmodium falciparum malaria in different seasons of the year in Khyber Teaching Hospital, Peshawar. METHODS A total of(More)
The FastDES algorithm is based on Data Encryption Standard (DES). In FastDES, the one round function concept of DES are used in three different customs to produce a new fast and more efficient secure algorithm. The DES operates on half of the input data, 32-bit of chunk out of 64 bits, while FastDES take block of 32-bit and work on it simultaneously. The(More)
As the number of network service provider's increases so the numbers of handoffs are increases to avail the best quality of services within affordable cost. In such scenarios fast and secure handoff is obligatory but diversification always creates worries of intruders and latency due to heterogeneous architectures with multiple access points. And(More)
