Preferred tools for WarDriving are as follows:-

a) Kismet- Kismet is a 802.11b wireless network sniffer. It is capable of sniffing using almost any wireless card supported in Linux.
b) Airsnort- is one of the first tools to come out discovering insecurity of wireless network. AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.
c) WEPCrack is Perl based tool. WEPCrack is a tool that cracks 802.11 WEP encryption keys using the latest DISCOVERED weakness of RC4 key scheduling.
d) WaveStumbler is console based 802.11 network mapper for Linux. It REPORTS the basic AP stuff like channel, WEP, ESSID, MAC etc.
e) Aircrack YET another WEP cracking tool for Linux courtesy by DIVINE.
