Links between nodes may constantly change due to mobility. The performance of the transmission control protocol (TCP) degrades in such an environment mainly due to its inability to differentiate between congestion and link failures which are frequent in MANETs. Several TCP variants were proposed to adapt TCP to a mobile environment. In addition, other reliable transport protocols were especially designed for MANETs as an alternative to these TCP variants. Several network settings might require different transport protocols to coexist and interoperate. In this paper we present a model that can be used to achieve interoperability between reliable transport protocols. The proposed model consists of forming an intermediate easy-to-implement thin layer between the network layer and the transport layer in the TCP/IP stack. Such layer will be invoked at the receiver side and will preserve the semantics of the sender's transport protocol. Our proposed model focuses on TCP and ATP, the ad-hoc transport protocols, but it can be expanded to accommodate other protocols.","PeriodicalId":211631,"journal":{"name":"2011 International Conference on Communications and Information Technology (ICCIT)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122701670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SAC is said to be satisfied if, whenever a single input bit is complemented, each of the output bits changes with a probability of one half. In terms of the block ciphers context, such a small change in either the key or the plaintext should cause a drastic change in the ciphertext. Consequently catastrophic error results when decrypting the ciphertext. Although this criterion is desirable to assure security, these algorithms do not take into account the bit error characteristics of the wireless channel. If an error occurs in the encrypted data over the channel, which is highly likely in wireless channels, the decryption process at the receiver results in half the original bits to be in error due to the SAC effect. Therefore, the need for new secure encryption algorithm that takes into account the bit error characteristics of the wireless channel becomes necessary. In this paper, we present two methods to tackle this effect while at the same time not tolerating security. We first present a modification to the way the traditional Data Encryption Standard (DES) itself is performed to make it prone to errors caused by the wireless channel. Secondly, we present a modification to the way encrypted data is transmitted over the channel. The two proposed methods are shown to achieve less SAC effect and hence improved error performance, higher data rates, and at at least as secure as traditional encryption algorithms. We assume the additive white Gaussian noise (AWGN) channel model in our analysis.","PeriodicalId":211631,"journal":{"name":"2011 International Conference on Communications and Information Technology (ICCIT)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133239683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
