This paper presents a study for the transmission of images over mobile Bluetooth networks. It presents a novel chaotic interleaving scheme for this purpose. In this scheme, the chaotic Baker map is used for bit interleaving and enhanced data rate packets are used for data trans- mission. In the proposed scheme, the chaotic interleaver can be applied on the whole bit stream or on a packet- by-packet basis. The proposed scheme is applied with 2DH 1 , 2DM 1 , 3DH 5 , and 3DM 5 packets. A comparison study between the proposed scheme and the traditional interleaving schemes for image transmission over corre- lated and uncorrelated fading channels is presented. The simulation results show the superiority of the proposed scheme over the traditional schemes. The proposed scheme also adds a degree of security to data transmission. Keywords Mobile wireless networks  Chaotic Baker map  Interleaving techniques 1 Introduction With the increase in utilization of wireless devices, espe- cially Bluetooth devices, power reduction and throughput maximization have become challenging tasks. Bluetooth is designed to transfer data using asynchronous connection- less (ACL) packets and synchronous connection-oriented (SCO) packets. It has emerged as a wireless communica- tion technology for achieving the interconnection between computer peripherals in an efficient manner. Also, it is used for self-established and configured wireless ad-hoc net- works [1, 2]. Bluetooth operates in distances up to 100 meters. The stations in the different Bluetooth versions follow a piconet structure. Each piconet comprises up to seven Bluetooth devices working as Slave (S) stations and only one Blue- tooth device working as a Master (M) station. A slave can be a member in more than one piconet. A master of any piconet may be a slave in another one. Up to 10 piconets may exist in the Bluetooth range [3, 4]. Bluetooth operates in the unlicensed 2.4 GHz Industrial Scientific Medical (ISM) frequency band, which is also utilized by other various wireless and radio technologies M. A. M. El-Bendary  M.
